Bis(ÎĽ-2,2′-{[4-(carbÂoxyÂmethÂoxy)phenÂyl]azaÂnediÂyl}diacetato)ÂbisÂ[(1,10-phenanthroline)copper(II)]
The crystal structure of the binuclear title compound, [Cu2(C12H11NO7)2(C12H8N2)2], consists of a complex molÂecule, which lies about a crystallographic inversion centre with one half-molÂecule in the asymmetric unit. The CuII cation is bonded to three N atoms and three O atoms, in a Jahn–Teller-distorted octaÂhedral geometry. The basal plane is defined by the two N atoms from the 1,10-phenathroline and two deprotonated O atoms of the polycarboxylÂate ligand. The axial positions are occupied by the azane N atom and a bridging carboxylÂate O atom from the second polycarboxylÂate ligand. The complex molÂecules are linked through O—Hâ‹ŻO hydrogen bonds into extended chains running parallel to [010]
