Abstract

In the title cooridnation polymer, {[Cu(C6H2O5)(C3H4N2)2(H2O)]·3H2O}n, an infinite chain is formed along [001] by linking of the Cu(C3N2H4)2(H2O) entities with two bridging monodentate carboxyl­ate groups of two different furan-2,5-dicarboxyl­ate dianions. The geometry of the Cu2+ ion is a square-based pyramid with the water atom in the apical position and the ligand O and N atoms in a trans orientation. The dihedral angle between the imidazole planes is 83.96 (14)°. Ow–H⋯O and Ni–H⋯O (w = water and i = imidazole) hydrogen bonds help to establish the packing.
