catena-Poly[[aqua(2,2′-bipyridine-κ2N,N′)copper(II)]-μ-5-nitroisophthalato-κ3O1,O1′:O3]

In the asymmetric unit of the title compound, [Cu(C8H3NO6)(C10H8N2)(H2O)]n, there are two symmetry-independent one-dimensional coordination polymers related by a non-crystallographic inversion center. Within the polymers, the CuII atoms, coordinated by the water molecule and the chelating 2,2′-bipyridine ligands, are bridged by 5-nitrobenzene-1,3-dicarboxylate dianions which act as tridentate ligands; the carboxylate groups exhibit monodentate and symmetric bidentate coordination modes. The CuII atoms show a strongly distorted octahedral coordination geometry. In the crystal structure, the two symmetry-independent coordination polymers form another one-dimensional polymeric structure via O—H...O hydrogen bonds between coordinated water molecules and carboxylate groups
