摘      要：A new 2,2＂-bipyridine adduct of bis（O,O＇-di（2-phenylethyl）dithiophosphato） cadmium（II）, [Cd{S2P（OCH2CH2Ph）2}2＂bipy] （1, bipy -- 2,2＂-bipyridine）, was synthesized and characterized by elemental analyses, IR, UV-vis, 1H NMR, fluorescence spectroscopy, thermo-gravimetric analysis, and X-ray single-crystal diffraction. The crystal of 1 crystallizes in triclinic, space group P1 with a = 10.4607（19）, b = 11.679（2）, c = 18.480（3） A, a = 98.900（2）, β = 103.321（2）, ）, = 91.779（2）, V= 2165.2（7） A3, Dc = 1.447 g/cm3, Z = 2, C42H4404N2P2S4Cd, Mr = 943.37, F（000） = 968,μ = 0.814 mm-1, the final R = 0.0536 and wR = 0.1206 for 6275 observed reflections with 1 〉 2a（/） and R = 0.0690 and wR = 0.1339 for all data. The result shows that the Cd（1） centre is five-coordinated by two N and three S atoms in a highly distorted square pyramidal configuration. The C-H＇＂S hydrogen bonding interactions and a set of weak intermolecular r-r stacking between adjacent aromatic rings stabilize the structure and make 1 assemble into a 1D zig-zag chain. In addition, the antibacterial activities of 1 against Escherichia coli, Bacillus subtilis and Staphylococcus bacteria were also screened by disc diffusion method.
