摘要
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.
