摘要:
The compound [Cu(TSC)(2)](H(2)SSal)(2) (I) has been synthesized (TSC is thiosemicarbazide, H(3)SSal is 5-sulfosalicylic acid) and studied by IR spectroscopy and X-ray crystallography. The crystals of I are triclinic: a = 6.728(2) , b = 7.772(1), c = 11.600(6), alpha = 88.60A degrees, beta = 86.68(3)A degrees, gamma = 79.22(4)A degrees, V = 594.8(4)(3), Z = 2, space group P(1) over bar. The structural units of the crystal are the centrosymmetric [Cu(TSC)(2)](2+) cation, in which the Cu atom is in a square-planar coordination formed by the bidentate chelating (N,S) TSC ligands, and (H(2)SSal)(-) anions (Cu(1)-N(3), 2.013(3) ; Cu(1)-S(1), 2.275(1) ). The coordination polyhedron of the Cu(1) atom is completed to a prolate tetragonal bipyramid (4 + 2) by Cu-O bonds (2.810(3) ) of the sulfate moieties of both anions, which form together with hydrogen bonds the [Cu(TSC)(2)(H(2)SSal)(2)] supermolecule. The complex cations are packed in layers and alternate with anion-containing layers. Hydrogen bonding and pi-pi stacking interactions are responsible for formation of supramolecular layer ensembles.
