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

Abstract

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 P21/c space group with the unit cell parameters: a = 9.4917(4) A, b = 22.2895(11) A, c = 11.3300(5) A, β = 117.433(3)°, V = 2127.49(17) A3, 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. The synthesis and structure of a thiocyanato-bridged one-dimensional supramolecular, [Cd(NCS)2 (TPPO)] n (1, TPPO = triphenylphosphine oxide), have been described.
