A copper（Ⅰ） complex with N,N′-diphenyl thiourea［C32H38ClCuN6O2S2］ was synthesized by a facile method of in situ reduction of copper（Ⅱ） to copper（Ⅰ）.The structure was characterized by elemental analysis,IR and X ray single-crystal diffraction.The crystal structure of the complex belongs to monoclinic system with space group P21/c.The cell parameters were as follows:a=0.957 4（5） nm，b=3.210 7（17） nm，c=1.222 8（7） nm;β=111.877（8）°，V=3.488（3） nm3，Z=4，Dc=1.336 mg/m3,F（000）=1 464,and the final structure deviation factor R1=0.047 5，ωR2=0.130 7.Based on multiplicate intermolecular hydrogen bonds,three-dimentional supramolecular structure in the complex was fabricated in solid phase.Additionally,the spectral property,thermal stability and electrochemical behavior of the complex were also studied in order to provide a valuable reference and a theoretical basis for further study of the structures and functional properties of this kind of metal-organic complexes.
