摘　　要：合成了2个苯甲羟肟酸有机锡配合物:[(o-Cl-C_(6)H_(4)CH_(2))_(2)Sn(C_(6)H_(5)CONO)_(2)](1)和[(o-CH3-C_(6)H_(4)CH_(2))_(2)Sn(C_(6)H_(5)CONO)(C_(6)H_(5)COO)](2)。通过元素分析、红外光谱、核磁共振氢谱、热重分析、单晶X射线衍射等方法对配合物进行了结构表征,对其结构进行量子化学从头计算和体外抗癌活性研究。结果显示:配合物均为单锡核结构,配合物1为六配位的畸变八面体构型,配合物2为五配位的畸变三角双锥构型;配合物1对人宫颈癌细胞(HeLa)、肝癌细胞(HuH-7)和肺腺癌细胞(H1975)显示出比临床使用的顺铂强的抑制活性,而配合物2的抑制活性要弱得多。Two benzohydroxamic acid organotin complexes[(o-Cl-C_(6)H_(4)CH_(2))_(2)Sn(C_(6)H_(5)CONO)_(2)](1)and[(o-CH3-C_(6)H_(4)CH_(2))_(2)Sn(C_(6)H_(5)CONO)(C_(6)H_(5)COO)](2)were synthesized by solvothermal method using methanol as a solvent.Complexes 1 and 2 were characterized by elemental analysis,IR,1H NMR,thermogravimetric analysis,singlecrystal X-ray diffraction,etc.The study on the complexes has been performed with quantum chemistry calculation and in vitro anticancer activity.The results show that the two complexes are monotin nuclear structures;complexes 1 and 2 are the six-coordinated distorted octahedron configuration and seven-coordinated distorted triangular bipyramid configuration,respectively.Complex 1 showed stronger inhibitory activity on human cervical cancer cells(HeLa),hepatoma cells(HuH-7),and lung adenocarcinoma cells(H1975)than cisplatin,while complex 2 showed much weaker inhibitory activity.CCDC:2253738,1;2253739,2.
