Abstract

AbstractTwo new inorganic–organic vanadate hybrid compounds [Mn(Hbbi)2(V4O12)] (1) and [Cd(Hbbi)2(V4O12)] (2) (bbi = 1,1’‐(1,4‐butanediyl)bis(imidazole)) were hydrothermally synthesized and characterized by elemental analyses, IR spectroscopy, TG and single‐crystal X‐ray diffraction. The two compounds crystallize in monoclinic system, P21/c space group with a = 8.556(5) Å, b = 10.761(5) Å, c = 16.917(5) Å, β = 93.032(5) o, V = 1555.4(12) Å3, Z = 2, R = 0.0390 for 1 and a = 8.657(5) Å, b = 10.743 (5) Å, c = 16.864 (5) Å, β = 93.81(5)o, V = 1564.9 (12) Å3, Z = 2, R = 0.0717 for 2. Single‐crystal X‐ray diffraction analysis reveals that the two compounds are isostructural and both consist of one‐dimensional (1D) chains, which are constructed from vanadate anion clusters and [M(Hbbi)2]4+ cation groups [M = MnII (1), CdII (2)]. Moreover, the polymeric chains are ultimately packed into a three‐dimensional (3D) supramolecular framework through C–H···O and N–H···O hydrogen bonding interactions.
