In the title inorganic–organic hybrid compound, [Cu2V4O12(C3H4N2)8]n, the VV ion is tetracoordinated by four O atoms and the CuII ion is hexacoordinated by four N atoms from four imidazole ligands and two O atoms from two tetrahedral vanadate (VO4) units in a distorted octahedral geometry. The structure consists of two-dimensional sheets constructed from centrosymmetric cyclic [V4O12]4− anions covalently bound through O to [Cu(imidazole)4]2+ cations. Adjacent sheets are linked by N—HO hydrogen bonds and weak C—Hπ interactions (Hcentroid distances = 2.59, 2.66, 2.76, 2.91 and 2.98 Å into a three-dimensional supramolecular network.
