| 摘要: 合成了2种新的N-甲基-N-苄基二硫代氨基甲酸锑[Sb（MeBnNCS2）3]（1）和铋[Bi（MeBnNCS2）3]（2）配合物。通过元素分析、红外光谱、1H NMR、热重对其进行表征，并用X-射线单晶衍射测定了晶体结构。配合物1和2均属于单斜晶系，P21/c空间群。配合物1的晶胞参数为：a=0.9551（7）nm，b=1.3575（10）nm，c=2.4681（17）nm，β=104.01（2）°，Z=4，V=3.105（4）nm3，Dc=1.520g·cm-3，F（000）=1440，μ=1.314mm-1，最终偏离因子R1=0.0339，wR2=0.0832，S=1.010；配合物2的晶胞参数为：a=1.3390（6）nm，b=0.9975（5）nm，c=2.4261（5）nm，β=98.433（7）°，Z=4，V=3.205（2）nm3，Dc=1.653g·cm-3，F（000）=1568，μ=5.912mm-1，最终偏离因子R1=0.0398，wR2=0.0864，S=1.089。在这2个配合物中，中心金属离子M（Ⅲ）与来自3个配体中的6个硫原子配位，配合物1形成6配位的畸变的八面体构型；配合物2则形成6配位的畸变的五角锥构型。在配合物2中，分子之间又通过Bi…S弱相互作用构成二聚体结构。利用琼脂扩散法测试了配合物的抑菌活性，结果表明配合物1对4种受试菌株具有较强的抑菌活性。 |

| Abstract: Two novel complexes [Sb(Ⅲ)(MeBnNCS2)3] (1) and [Bi(Ⅲ)(MeBnNCS2)3] (2) were synthesized and characterized by elemental analysis, IR, 1H NMR, TG-DTG and X-ray single-crystal diffraction. Both complexes belong to monoclinic system, P21/c space group, for 1: a=0.9551(7) nm, b=1.3575(10) nm, c=2.4681(17) nm, β=104.01(2)°, Z=4, V=3.105 (4) nm3, Dc=1.520 g·cm-3, F(000)=1440, μ=1.314 mm-1, the final R1=0.0339, wR2=0.0832, S=1.010, for 2: a=1.3390(6) nm, b=0.9975(5) nm, c=2.4261(5) nm, β=98.433(7)°, Z=4, V=3.205(2) nm3, Dc=1.653 g·cm-3, F(000)=1568, μ=5.912 mm-1, the final R1=0.0398, wR2=0.0864, S=1.089. The central M(Ⅲ) are coordinated by six sulfur atoms from three legends, completing distorted octahedral coordination environment in 1 and pentagonal pyramid configuration in 2. For 2, the adjacent molecules are formed the dimmer structure by the weak interactions of Bi…S. The complexes were valued for their antimicrobial activities by agar diffusion method. The results indicate that the complex 1 to be active against the four test bacterial organisms. |
