Two Hybrid Compounds Constructed from Vanadate Clusters and Secondary Metal‐Bis(imidazole) Subunits

Two 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 = Mn^II ( 1 ), Cd^II ( 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.
