-biphenyl-2,2'-dicarboxylato)bis[aqua(4,4'-dimethyl-2,2'-bipyridine-
2N,N')copper(II)]The molecule of the title binuclear copper(II) complex, [Cu2(C14H8O4)2(C12H12N2)2(H2O)2], is bisected by a crystallographic twofold axis. Each CuII atom is coordinated in a distorted octahedral geometry by three O atoms from two biphenyl-2,2'-dicarboxylate anions, one aqua O atom and two N atoms of a 4,4'-dimethyl-2,2'-bipyridine ligand. Intramolecular O-H
O hydrogen bonds between the coordinated water molecules and the carboxylate O atoms are also present.
The title complound was synthesized hydrothermally in a Teflon-lined autoclave (25 ml) by heating a mixture of H2bpdc (0.2 mmol), dbpy (0.4 mmol) and CuSO4.5H2O (0.2 mmol) in water (10 ml) at 393 K for 3 d. Crystals suitable for X-ray analysis were obtained.
All H atoms were included in calculated positions, with C—H bond lengths fixed at 0.96 Å (methyl CH3), 0.93Å (aryl group) and O—H = 0.85 Å and were refined in the riding-model approximation. Uiso(H) values were calculated at 1.5 Ueq(C) for methyl groups and 1.2 Ueq(C) otherwise.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

The title binuclear copper(II) complex, [Cu2(C14H8O4)2(C10H8N2)2(H2O)2], is a centrosymmetric dimer. The asymmetric unit consitsts of one CuII atom, one 4,4'-dimethyl-2,2'-bipyridine (dbpy) ligand, one [1,1'-biphenyl]-2,2'-dicarboxylate dianion (bpdc2-) and a coordinated water molecule.
The CuII atom is six-coordinated by two N atoms from bpy and four O atoms, three from two bpdc2- anions and one from coordinated H2O, in a distorted octahedron coordination geometry. And it is noteworthy that the two CuII ions in the complex are bridged by two bpdc2- dianions, one is in a bis-monodentate mode whereas the other is in a bis-bidentate mode.
