摘要:An infinite one-dimensional cadmium metal-organic chain, namely catena-poly[aquabis(μ3-2,2′-{[1,2-phenylenebis(methylene)] bis(sulfanediyl)}dibenzoato)dicadmium(II)], [Cd2(C22H 16O4S2)2(H2O)] n, was synthesized by solvothermal reaction of Cd(NO 3)2·4H2O and 2,2′-{[1,2- phenylenebis(methylene)]bis(sulfanediyl)}dibenzoic acid (H2 L). The CdII centres have six-coordinate CdS2O4 and CdSO5 geometries. Due to the flexible -CH2-S- arms, the L 2- ligand adopts both syn and anti conformations. Four Cd II cations are linked by two syn L 2- ligands to form a centrosymmetric planar tetranuclear CdII core, which is further extended through bonding to the anti L 2- ligands to form a one-dimensional metal-organic chain. Adjacent one-dimensional chains are connected by C - H?π interactions and nonclassical C - H?O hydrogen bonds to form the resultant three-dimensional supramolecular framework.
