主　　题：5-chlorosalicylaldehyde derivative crystal structure Schiff base 

摘      要：The title compound （C28H32CdCl2N4O2S2, Mr = 704.00） has been synthesized and characterized by elemental analysis and single-crystal X-ray diffraction. The Schiff base compound is a derivative of 5-chlorosalicylaldehyde. As expected, the molecular structure adopts a trans configuration about the central C=N double bond. It crystallizes in the monoclinic system, space group P21/n with a = 6.003（5）, b = 16.490（15）, c = 15.698 （14） A,β = 94.523（12）°, V= 1549（2） A^3, Z = 2, Dc = 1.509 g/cm^3, F（000） = 716 and μ = 1.044 mm^-1. A total of 7724 reflections were collected in the range of 2.47-25.01° by using an phi and omega scantechnique, of which 2695 were unique （Rint = 0.0341） and 2258 observed reflections with 1 〉 2σ（I） were used in the structure solution and refinement. The complex assumes a distorted octahedral coordination geometry formed by four thiocyanate anions and two Schiff base ligands. The thiocyanate anion bridges the neighboring Cd（Ⅱ） atoms to form the polymeric chains.
