摘要
用扑酸(H2pa,2,3-diphenylpropionic acid)和三烃基锡氯化物R3SnCl(R=Ph,Bu,Me)合成了3个有机锡配合物{[(Ph3Sn)(pa)]·Et3N}n(1)、(Bu3Sn)2(pa)(2)和[(Me3Sn)2(pa)]·CH2Cl2(3)。通过元素分析、红外光谱、核磁共振谱及X-ray单晶衍射等手段对配合物进行了表征。结构表明三苯基锡扑酸酯为一维链状聚合物,扑酸作为桥联配体链接各个锡原子,中心锡采取五配位的三角双锥构型;而三甲基锡和三丁基锡扑酸酯配合物为二核锡配合物,锡采取四配位的四面体构型。
Three organotin(Ⅳ) complexes {[(Ph3Sn)(pa)]·Et3N}n(1)、 (Bu3Sn)2(pa) (2) and [(Me3Sn)2(pa)]·CH2Cl2(3) were synthesized by the reaction of pamoic acid (H2pa, 2, 3-diphenyl-propionic acid) and the corresponding triorganotin chloride R3SnCl (R=Ph, Bu, Me). All the complexes were characterized by elemental analysis, FTIR, NMR (1H, 13C, 119Sn) spectroscopy and single crystal X-ray diffraction. Structural analyses have revealed that the complex 1 is an infinite polymeric chain, in which each tin atom is linked by the bidentate bridging pamoic acid ligand, the center tin atom adopts a five-coordinated distorted trigonal bipyramidal geometry. However, the complexes 2 and 3 show dinuclear tin structure, the center tin atoms adopt four-coordinated distorted tetrahedral geometry. CCDC: 727157, 1; 892440, 2; 732076, 3.
