Synthesis and Crystal Structure ofa Bipy Bridged Binuclear Cu^Ⅱ Complex Containing Aminomethanesulfonic Acid [Cu2（Sams）2（Bipy）（H2O）2]·（H2O）

The title complex [Cu2（Sams）2（H2O）2（bipy）]·（H2O） 1 （H2Sams = N-（2-hydroxybenzy） aminomethanesulfonic acid, bipy = 4,4′-bipyridine） has been synthesized by the reaction of Cu- （CH3COO）2·H2O, nESams and 4,4′-bipyridine in aqueous methanol. It was characterized by IR, elemental analysis, thermogravimetric analysis （TGA） and X-ray diffraction analysis. Complex 1 crystallizes in monoclinic, space group P21/n with a= 10.9533（17）, b = 8.3408（13）, c = 16.714（3） A^°, β = 101.295（4）°, V = 1494.3（4） A^°3 and Z = 2. The asymmetric unit is comprised of a tridentate Schiff base Sams^2- anionic ligand, a 4,4′-bipyddine and two coordinated water molecules, thus forming a binuclear copper（Ⅱ） complex. The coordination environment at Cu^Ⅱ center is described as a slightly distorted square pyramidal geometry. Via intermolecular hydrogen bonds C（10）-H（10）…O（3） and C（13）- H（13）…O（3）, an infinite supramolecular chain is yielded. A number of intermolecular hydrogen bonds greatly contribute to the stabilization of the solid-state structure for 1.
