Synthesis and Structure of a Thiocyanato-Bridged One-Dimensional CdII Coordination Polymer

Synthesis and structure of a new thiocyanato-bridged one-dimensional coordination polymer, [Cd(NCS)(2)(TPPO)] (n) (1, TPPO = triphenylphosphine oxide), have been described. The title compound crystallizes in the monoclinic P2(1)/c space group with the unit cell parameters: a = 9.4917(4) , b = 22.2895(11) , c = 11.3300(5) , beta = 117.433(3)A degrees, V = 2127.49(17) (3), and Z = 4. The single crystal X-ray diffraction revealed that the structure of 1 features thiocyanate bridges and 1D zigzag chains. The chains consist of thiocyanato-bridged five-coordinated Cd atoms. And the coordination fashion of thiocyanate group is different from the previous reported five-coordinated Cd-NCS systems.
