title: Bis(μ-2,2'-{[4-(carb-oxy-meth-oxy)phen-yl]aza-nedi-yl}diacetato)-bis-[(1,10-phenanthroline)copper(II)].
abstract: 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 mol-ecule, which lies about a crystallographic inversion centre with one half-mol-ecule in the asymmetric unit. The Cu(II) cation is bonded to three N atoms and three O atoms, in a Jahn-Teller-distorted octa-hedral geometry. The basal plane is defined by the two N atoms from the 1,10-phenathroline and two deprotonated O atoms of the polycarboxyl-ate ligand. The axial positions are occupied by the azane N atom and a bridging carboxyl-ate O atom from the second polycarboxyl-ate ligand. The complex mol-ecules are linked through O-H⋯O hydrogen bonds into extended chains running parallel to [010].
