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.
