Poly[octakis(1H-imidazole-κN3)octa-μ-oxido-tetraoxidodicopper(II)tetravanadate(V)]

Abstract

In the title inorganic–organic hybrid compound, [Cu2V4O12(C3H4N2)8]n, the VVion is tetracoordinated by four O atoms and the CuIIion 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—H...O hydrogen bonds and weak C—H...π interactions (H...centroid distances = 2.59, 2.66, 2.76, 2.91 and 2.98 Å into a three-dimensional supramolecular network.
