catena-Poly[[[diaquacopper(II)]-{μ-4,4′-[1,4-phenylenebis(methyleneimino)]dibenzoato}] monohydrate]

Abstract

The asymmetric unit of the title polymeric compound, {[Cu(C22H18N2O4)(H2O)2]·H2O}n, contains a Cu ion situated on an inversion center, half of a centrosymmetric 4,4′-[1,4-phenylenebis(methyleneimino)]dibenzoate ligand, a coordinated water molecule in a general position and an uncoordinated water molecule situated on a twofold rotation axis. The distorted octahedral coordination geometry of the CuII ion is formed by six O atoms. The –NH– groups of the ligand are involved in intramolecular N—H...O hydrogen bonds, while the water molecules participate in the formation of a three-dimensional supramolecular framework via intermolecular O—H...O hydrogen bonds.
