摘　　要：The three-dimensional complex [Cd（μ1,3-SCN）（μ3-pco）]n has been synthesized with μ1,3-SCN^- and pco as mixed bridged ligands. The crystal belongs to monoclinic, space group P21/n with a = 10.3777（16）, b = 6.2592（9）, c = 13.150（2） A, β= 97.317（2）°, V= 847.2（2） A^3, Z= 4, C6H3CdN3O3S, Mr = 309.575, Dc = 2.427 g/cm^3, F（000） = 592 and μ = 2.804 mm^-1. The structure was refined to R = 0.0255 and wR = 0.0550 for 1712 observed reflections （1 〉 2σ（I））. In the crystal the Cd（Ⅱ） ions are coordinated by μ1,3-SCN^- and μ3-pco bridge ligands to form a three-dimensional structure.The three-dimensional complex [Cd（μ1,3-SCN）（μ3-pco）]n has been synthesized with μ1,3-SCN^- and pco as mixed bridged ligands.
