Abstract
<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>
