CRYSTAL AND MOLECULAR-STRUCTURE OF DI-MU-CHLOROBIS[2-[[[(2-HYDROXY-1-NAPHTHYL)METHYL]-IMINO]ETHANOLATO]N,O,O']DI-COPPER(II) DIHYDRATE

The crystal structure of the title compound has been determined from three-dimensional, single crystal X-ray diffraction data. [Cu2Cl2(C13H12NO2)2] . 2H(2)O crystallizes in the orthorhombic space group P2(1)2(1)2(1) with lattice constants, a = 11.866(2), b = 13.555(3), c = 17.380(3)Angstrom. Final full-matrix least-squares refinement of 3735 unique reflections yielded R = 0.054. The structure consists of dimeric C26H24C12Cu2N2O4 molecules and water molecules connected with the dimeric molecules by a hydrogen bond system. Both of the copper(II) centers are five-coordinated by two trans oxygen atoms and one nitrogen atom from one ligand molecule and two chloride ions, The geometry at each copper(II) center is best described as distorted tetragonal pyramidal. The apical Cu1-C12 and Cu2-C11 distances are 2.747(2) and 2.938(3)Angstrom, respectively. The Cu ... Cu separation is 3.496(1)Angstrom. The comparison with previously reported crystal structure of [Cu2Cl2 (C13H12NO2)(2)] . 1/2H(2)O is given.
