Bis(μ-2,2′-{[4-(carb­oxy­meth­oxy)phen­yl]aza­nedi­yl}diacetato)­bis­[(1,10-phenanthroline)copper(II)]

The crystal structure of the binuclear title compound, [Cu(2)(C(12)H(11)NO(7))(2)(C(12)H(8)N(2))(2)], consists of a complex mol­ecule, which lies about a crystallographic inversion centre with one half-mol­ecule in the asymmetric unit. The Cu(II) cation is bonded to three N atoms and three O atoms, in a Jahn–Teller-distorted octa­hedral geometry. The basal plane is defined by the two N atoms from the 1,10-phenathroline and two deprotonated O atoms of the polycarboxyl­ate ligand. The axial positions are occupied by the azane N atom and a bridging carboxyl­ate O atom from the second polycarboxyl­ate ligand. The complex mol­ecules are linked through O—H⋯O hydrogen bonds into extended chains running parallel to [010].
