title: 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 Cu(II) cation, located on a twofold rotation axis, is coordinated by one water mol-ecule and two imidazole mol-ecules as well as two symmetry-related 3-([4-[(2-carboxyl-atoeth-yl)carbamo-yl]phen-yl]formamido)-propano-ate dianions (L (2-)) in an approximately square-pyramidal geometry. The coordinating water mol-ecule is located on a twofold rotation axis while the L (2-) anion sits about an inversion center. The L (2-) anions bridge the Cu(II) 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 inter-action link the polymeric chains and the solvent water mol-ecules into a three-dimensional supra-molecular architecture.
