摘要：

A three-dimensional complex [Cd(μ1,3-SCN)2(dmpo)]n has been synthesized with μ1,3-SCN and dmpo as mixed bridge ligands. The crystal belongs to monoclinic, space group C2/c with a = 15.648(2), b = 15.126(2), c = 11.9773(15) , β = 112.416(2)°, V = 2620.7(6) 3, Z = 8, C9H9CdN3OS2, Mr = 351.71, Dc = 1.783 g/cm3, F(000) = 1376 and μ = 1.967 mm1. The structure was refined to R = 0.0260 and wR = 0.0647 for 2186 observed reflections (I > 2σ(I)). In the crystal the Cd(II) ions are coordinated by μ1,3-SCN bridge ligands to form the crossing chains on the adjacent planes, and these chains are further joined by μ-dmpo mono-dentate bridge ligands leading to a three-dimensional structure. The complex exhibits strong fluorescent emission property.
