摘要
Two novel complexes,[（C9H18NS2）3Sb（III）]（1） and [（C9H18NS2）3Bi（III）]（2）,were synthesized and characterized by elemental analysis,IR,TG and X-ray single-crystal diffraction.Both 1 and 2 crystallize in the monoclinic system,P21/c space group.The data for 1：a = 1.6964（3）,b = 1.02149（17）,c = 2.5650（3） nm,β = 121.824（8）°,Z = 4,V = 3.7766（10） nm^3,Dc = 1.293 g·cm^-3,F（000） = 1536,μ = 1.082 mm^-1,the final R = 0.0500,wR = 0.1562 and S =1.072.The data for 2：a = 1.6802（9）,b = 1.0256（6）,c = 2.5083（10） nm,β = 121.77（3）°,Z = 4,V = 3.675（3） nm^3,Dc = 1.486 g·cm^-3,F（000） = 1664,μ = 5.159 mm^-1,the final R = 0.0481,wR = 0.1055 and S =1.076.The coordinated geometry of the central M（III） with six sulfur atoms from three ligands is a distorted pentagonal pyramid configuration.The dimer structural system is formed by the weak interactions of M…S and C-H…S between two molecules.The complexes were valued for their antibacterial activities by agar-streak method.It was found that 1 is active against the four test bacterial organisms.
