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

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-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 Cu(II) 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.
