| 摘 要： | 1 INTRODUCTION The investigation of coordination polymers has rapidly been expanded in last decade owing to their potential applications such as catalysis, molecular absorption, non-linear and magnetic materials. Among the varieties of such coordination polymers, the po- lymers of cadmium with dicarboxylates having fas- cinating structural topologies and good photolumi- nescence constitute a new family. Many reports are concerned about cadmium dicarboxylate polymers with 1D helix structu… |

| Abstract: | A 2D lamellar metal-organic coordination polymer [2-(1,3)-dithian-2-ylidene malo- nate] diaquoicadmium(II) hydrate, [Cd(dym)(H2O)2(H2O)]n (dym = 2-(1,3)-dithian-2-ylidene malo- nate), has been prepared by conventional solution reaction. The structure analysis suggests that the polymer crystallized in orthorhombic system with space group Pbca and the final R indices (I >2σ(I)): R1 = 0.0236 and wR2 = 0.0738. Crystal data: a = 12.6138(5), b = 8.4528(3), c = 22.5867(8)(A), V = 2409.8(15)(A)3, Z = 3, F(000) = 1520, Dc = 1.482 g/cm3, μ(MoKα) = 0.990 mm-1 and Mr = 384.69 g/mol. The Cd(II) ion is in a disordered triangle prism environment. The Cd-O distances are in the range of 2.2643(14)～2.3641(15)(A).In the crystal, the Cd atoms are arranged at the corners of honeycomb-like hexagonal 24-membered macrometallacycle. There is a weak C-H…S interaction between the 1,3-dithiocyclohexyl groups of two adjacent dym ligands. |
