Crystal structure of catena-poly[[[aqua-bis-(1H-imidazole-κN (3))copper(II)]-μ-3-({4-[(2-carboxyl-atoeth-yl)carbamo-yl]phen-yl}formamido)-propano-ato-κ(2) O:O'] dihydrate

Abstract

In the title polymeric complex, {[Cu(C14H14N2O6)(C3H4N2)2(H2O)]·2H2O}n, the CuII cation, located on a twofold rotation axis, is coordinated by one water mol­ecule and two imidazole mol­ecules as well as two symmetry-related 3-([4-[(2-carboxyl­atoeth­yl)carbamo­yl]phen­yl]formamido)­propano­ate dianions (L 2−) in an approximately square-pyramidal geometry. The coordinating water mol­ecule is located on a twofold rotation axis while the L 2− anion sits about an inversion center. The L 2− anions bridge the CuII cations, forming polymeric chains propagating along the [101] direction. In the crystal, O—H⋯O, N—H⋯O hydrogen bonds and weak C—H⋯π inter­action link the polymeric chains and the solvent water mol­ecules into a three-dimensional supra­molecular architecture.
