  bibo_abstract:
  - We report the synthesis, structural elucidation, and establishment of structure−property
    relationships for two metal−organic frameworks (MOFs), [M(OH)(H2BPD)]·xH2O (M
    = Al3+, Ga3+, x = 11–13), denoted as M-CAU-67, employing the ditopic linker molecule
    N,N′-4,4′ bipiperidine bis(methylenephosphonic acid) (H4BPD). The title compounds
    can be synthesized on a milligram scale under hydrothermal conditions, while gram-scale
    synthesis was realized under reflux conditions. Single-crystal X-ray diffraction
    (SCXRD) revealed an isoreticular, expanded MIL-91 type structure, representing
    a rare case of isoreticular expansion in porous metal phosphonates. The framework
    structure was confirmed by Rietveld refinement against powder X-ray diffraction
    (PXRD) data and further validated by solid-state NMR spectroscopy (31P MAS, 27Al
    3Q MAS). Solvent-exchange experiments and variable-humidity/temperature PXRD data
    revealed high framework flexibility. The compounds show permanent microporosity
    and a complex, polarity- and size-dependent sorption behavior toward gases and
    vapors.@eng
