  text: <jats:title>Abstract</jats:title><jats:p>Synthesis and characterisation of
    a disubstituted phenanthroline, “dbt‐phen” (“dbt‐phen”, 2,9‐di(benzothiazolino)‐1,10‐phenanthroline)
    <jats:bold>1</jats:bold> and its Cu<jats:sup>I</jats:sup>, Cu<jats:sup>II</jats:sup>,
    Ni<jats:sup>II</jats:sup>, Zn<jats:sup>II</jats:sup> and Fe<jats:sup>II</jats:sup>
    complexes are reported. Three different coordination modes of the ligand <jats:italic>viz.,</jats:italic>
    bis(didentate), tridentate and tetradentate are observed. Under various experimental
    conditions, <jats:bold>1</jats:bold> forms a double‐stranded dicopper(I)helicate,
    [Cu<jats:sup>I</jats:sup><jats:sub>2</jats:sub>(dbt‐phen)<jats:sub>2</jats:sub>]<jats:sup>2+</jats:sup>
    <jats:bold>2</jats:bold>; a mono(dbt‐phen) copper(II) complex, [Cu<jats:sup>II</jats:sup>(dbt‐phen)(H<jats:sub>2</jats:sub>O)<jats:sub>2</jats:sub>]<jats:sup>2+</jats:sup>
    <jats:bold>3,</jats:bold> a Ni<jats:sup>II</jats:sup> complex [Ni(dbt‐ phen)(NCMe)<jats:sub>2</jats:sub>(OH<jats:sub>2</jats:sub>)]<jats:sup>2+</jats:sup>
    <jats:bold>4</jats:bold>, a bis(dbt‐phen) zinc(II) complex, [Zn<jats:sup>II</jats:sup>(<jats:italic>dbt‐phen</jats:italic>)<jats:sub>2</jats:sub>]<jats:sup>2+</jats:sup>
    <jats:bold>5</jats:bold> and a pseudo‐octahedral complex [Fe<jats:sup>II</jats:sup>(dbt‐phen)Br<jats:sub>2</jats:sub>]
    <jats:bold>6</jats:bold>. Crystal packing feature of the dicopper helicate [Cu<jats:sup>I</jats:sup>(<jats:italic>dbt‐phen</jats:italic>)]<jats:sub>2</jats:sub>[BF<jats:sub>4</jats:sub>]<jats:sub>2</jats:sub><jats:bold>,
    2</jats:bold>+[BF<jats:sub>4</jats:sub>]<jats:sub>2</jats:sub> reveals novel short
    contacts between BF<jats:sub>4</jats:sub><jats:sup>−</jats:sup> ions and the hydrogens
    of the phenyl rings leading to the peculiar double stranded and helical topology.
    The complex [Cu<jats:sup>II</jats:sup>(<jats:italic>dbt‐phen</jats:italic>)(OH<jats:sub>2</jats:sub>)<jats:sub>2</jats:sub>(ClO<jats:sub>4</jats:sub>)][ClO<jats:sub>4</jats:sub>],
    <jats:bold>3</jats:bold>+[ClO<jats:sub>4</jats:sub>] exhibits both intra‐ and
    inter‐molecular H‐bonding interactions. <jats:sup>1</jats:sup>H NMR spectral features
    of the ligand, copper(I) and zinc(II) complexes indicate that the free ligand
    and the copper(I) complex retain their solid state structures whereas the zinc(II)
    complex undergoes structural changes in solution.</jats:p>

    The stoichiometric reaction of the corresponding water‐free metal salts with the
    ligand btmgp in dry MeCN or THF resulted in the straightforward formation of the
    mononuclear complexes <jats:bold>1</jats:bold>–<jats:bold>7</jats:bold> and the
    binuclear complex <jats:bold>8</jats:bold>. In complexes with <jats:italic>M</jats:italic><jats:sup>II</jats:sup>
    the metal ion shows a distorted tetrahedral coordination whereas in <jats:bold>8</jats:bold>,
    the coordination of the <jats:italic>M</jats:italic><jats:sup>I</jats:sup> ion
    is almost linear. The coordination behavior of btmgp and resulting structural
    parameters of the corresponding complexes were discussed in an comparative approach
    together with already described complexes of btmgp and the bisguanidine ligand

  text: <jats:title>Abstract</jats:title><jats:p>A series of bis‐guanidine ligands
    designed for use in biomimetic coordination chemistry has been extended to a library
    matrix combining unprecedented substitutional flexibility within the guanidyl
    residues with a wide range of aliphatic and aromatic spacers connecting these
    functionalities. The underlying protocol can be used with predefined ureas as
    well as secondary amines to build up these units by reaction with phosgene if
    the ureas are otherwise unavailable. In the latter case, the resulting urea intermediates
    do not have to be isolated as the reaction proceeds further with additional phosgene
    to yield a chloroformamidinium chloride which is transformed into the bis‐guanidine
    functionality by subsequent reaction with a suitable primary diamine in the presence
    of triethylamine as an auxiliary base. This concept has been used to synthesise
    and characterise more then two dozen different bis‐guanidines based on 12 discrete
    monoguanidine units and seven different spacers. These spacers have been chosen
    such that the most important phenotypes have been dealt with and which range from
    rigid to more flexible scaffolds. In addition to spacers with no metal‐binding
    capabilities, other species containing further donor functions such as <jats:italic>N</jats:italic>‐methyldiphenyleneamine
    or pyridine‐2,6‐diyl have also been used. The substitution patterns of the guanidine
    residues can be classified into acyclic and cyclic types. Among the cyclic types,
    one subset is characterised by five‐ or six‐membered heterocycles containing both
    the amino nitrogen atoms and another one by individual N‐heterocyclic systems
    for each amino nitrogen. Structurally characterised examples are 2‐{2‐[2‐(tetramethylguanidi­no)ethoxy]ethoxy}‐1‐(tetramethylguanidino)ethane
    (TMG<jats:sub>2</jats:sub>doo) in its diprotonated form and 2,2′‐bis[2<jats:italic>N</jats:italic>‐(1,1′,3,3′‐tetramethylguanidine)]diphenyleneamine
    (TMG<jats:sub>2</jats:sub>PA) as wellas <jats:italic>N</jats:italic><jats:sup>1</jats:sup>,<jats:italic>N</jats:italic><jats:sup>3</jats:sup>‐bis(dimorpholinomethylene)propane‐1,3‐diamine
    (DMorphG<jats:sub>2</jats:sub>p) as free bases. For the permethylated bis‐guanidine
    derivatives, the barrier to rotation around the (C=N)<jats:sub>guanidine</jats:sub>
    bond has been determined by means of temperature‐dependent EXSY <jats:sup>1</jats:sup>H
    NMR spectroscopy to range between 54 and 79 kJ mol<jats:sup>–1</jats:sup> depending
    on the type of spacer. (© Wiley‐VCH Verlag GmbH &amp; Co. KGaA, 69451 Weinheim,

    of Chiral Metallatetrahedron Complexes of the Type [Re<jats:sub>2</jats:sub>(M<jats:sup>1</jats:sup>PPh<jats:sub>3</jats:sub>)(M<jats:sup>2</jats:sup>PPh<jats:sub>3</jats:sub>)(μ‐PCy<jats:sub>2</jats:sub>)(CO)<jats:sub>7</jats:sub>C≡CPh]
    (M<jats:sup>1</jats:sup> = Ag, Au; M<jats:sup>2</jats:sup> = Cu, Ag, Au)</jats:bold></jats:p><jats:p>From
    the reaction of Li[Re<jats:sub>2</jats:sub>(μ‐H)(μ‐PCy<jats:sub>2</jats:sub>)(CO)<jats:sub>7</jats:sub>(C(Ph)O)]
    (<jats:bold>1</jats:bold>) with Ph<jats:sub>3</jats:sub>AuC≡CPh both benzaldehyde
    and the trinuclear complex Li[Re<jats:sub>2</jats:sub>(AuPPh<jats:sub>3</jats:sub>)(μ‐PCy<jats:sub>2</jats:sub>)(CO)<jats:sub>7</jats:sub>C≡CPh]
    (<jats:bold>2a</jats:bold>) were obtained in high yield. The complex anion was
    isolated as its PPh<jats:sub>4</jats:sub>‐salt <jats:bold>2b</jats:bold>. The
    latter reacts with coinage metal complexes PPh<jats:sub>3</jats:sub>M<jats:sup>2</jats:sup>Cl
    [M<jats:sup>2</jats:sup> = Cu, Ag, Au] to give chiral heterometallatetrahedranes
    of the general formula [Re<jats:sub>2</jats:sub>(AuPPh<jats:sub>3</jats:sub>)(M<jats:sup>2</jats:sup>PPh<jats:sub>3</jats:sub>)(μ‐PCy<jats:sub>2</jats:sub>)(CO)<jats:sub>7</jats:sub>C≡CPh]
    (M<jats:sup>2</jats:sup> = Cu <jats:bold>3a</jats:bold>, Ag <jats:bold>3b</jats:bold>,
    Au <jats:bold>3c</jats:bold>). The corresponding complex [Re<jats:sub>2</jats:sub>(AgPPh<jats:sub>3</jats:sub>)<jats:sub>2</jats:sub>(μ‐PCy<jats:sub>2</jats:sub>)(CO)<jats:sub>7</jats:sub>C≡CPh]
    (<jats:bold>3d</jats:bold>) is obtained from the reaction of [Re<jats:sub>2</jats:sub>(AgPPh<jats:sub>3</jats:sub>)<jats:sub>2</jats:sub>(μ‐PCy<jats:sub>2</jats:sub>)(CO)<jats:sub>7</jats:sub>Cl]
    (<jats:bold>4</jats:bold>) with LiC≡CPh. <jats:bold>3d</jats:bold> undergoes a
    metathesis reaction in the presence of PPh<jats:sub>3</jats:sub>CuCl giving [Re<jats:sub>2</jats:sub>(AgPPh<jats:sub>3</jats:sub>)(CuPPh<jats:sub>3</jats:sub>)(μ‐PCy<jats:sub>2</jats:sub>)(CO)<jats:sub>7</jats:sub>C≡CPh]
    (<jats:bold>3e</jats:bold>) and PPh<jats:sub>3</jats:sub>AgCl. Analogous metathesis
    reactions are observed when <jats:bold>3c</jats:bold> is reacted with PPh<jats:sub>3</jats:sub>AgCl
    or PPh<jats:sub>3</jats:sub>CuCl giving <jats:bold>3a</jats:bold> or <jats:bold>3b</jats:bold>,
    respectively. The reaction of <jats:bold>1</jats:bold> with PPh<jats:sub>3</jats:sub>AuCl
    gives benzaldehyde and Li[Re<jats:sub>2</jats:sub>(AuPPh<jats:sub>3</jats:sub>)(μ‐PCy<jats:sub>2</jats:sub>)(CO)<jats:sub>7</jats:sub>Cl]
    (<jats:bold>5a</jats:bold>) which upon reaction with PhLi forms the trinuclear
    complex Li[Re<jats:sub>2</jats:sub>(AuPPh<jats:sub>3</jats:sub>)(μ‐PCy<jats:sub>2</jats:sub>)(CO)<jats:sub>7</jats:sub>Ph]
    (<jats:bold>6a</jats:bold>). Again this complex was isolated as its PPh<jats:sub>4</jats:sub>‐salt
    <jats:bold>6b</jats:bold>. In contrast to <jats:bold>2b</jats:bold>, <jats:bold>6b</jats:bold>
    reacts with one equivalent of Ph<jats:sub>3</jats:sub>PAuCl by transmetalation
    to give Ph<jats:sub>3</jats:sub>PAuPh and PPh<jats:sub>4</jats:sub>[Re<jats:sub>2</jats:sub>(AuPPh<jats:sub>3</jats:sub>)(μ‐PCy<jats:sub>2</jats:sub>)(CO)<jats:sub>7</jats:sub>Cl]
    (<jats:bold>5b</jats:bold>). The X‐ray structures of the compounds <jats:bold>3a</jats:bold>,
    <jats:bold>3b</jats:bold>, <jats:bold>3e</jats:bold> and <jats:bold>4</jats:bold>
    are reported.</jats:p>
