Abstract:
The asymmetric unit of the title polymeric compound, {[Cu(C(22)H(18)N(2)O(4))(H(2)O)(2)]·H(2)O}(n), contains a Cu ion situated on an inversion center, half of a centrosymmetric 4,4'-[1,4-phenyl-enebis(methyl-eneimino)]dibenzoate ligand, a coordin-ated water mol-ecule in a general position and an uncoordin-ated water mol-ecule situated on a twofold rotation axis. The distorted octa-hedral coordination geometry of the Cu(II) ion is formed by six O atoms. The -NH- groups of the ligand are involved in intra-molecular N-H⋯O hydrogen bonds, while the water mol-ecules participate in the formation of a three-dimensional supra-molecular framework via inter-molecular O-H⋯O hydrogen bonds.
