Structural chemistry of organotin carboxylates IV. Synthesis and spectroscopic properties of diorganotin(IV) complexes with o-anisic acid. The crystal and molecular structure of [nBu2Sn(2-MeOC6H4COO)]2O2
Reactions of diorganotin(IV) oxides with o-anisic acid in and stoichiometry afford complexes of the type [R2Sn(2-MeOC6H4COO)]2O2 (I) and [R2Sn(2-MeOC6H4COO)2] (II) (R = Me, Et, nPr, nBu), respectively. These complexes have been characterized by elemental analyses, IR and NMR (1H, 13C and 119Sn) spectroscopy, and I shown to adopt a dimeric ladder structure whereas II has the usual monomeric diorganotin
二有机锡(IV)氧化物与邻茴香酸的化学反应和化学计量得到[R 2 Sn(2-MeOC 6 H 4 COO)] 2 O 2(I)和[R 2 Sn(2-MeOC 6) H 4 COO)2 ](II)(R = Me,Et,n Pr,n Bu)。这些配合物已通过元素分析,IR和NMR(1 H,13 C和119Sn)光谱,I显示采用二聚体阶梯结构,而II具有通常的单体二有机锡二羧酸酯结构。配体的甲氧基的氧原子不参与与锡原子的键合。该结论得到X射线衍射研究的支持。化合物[ n Bu 2 Sn(2-MeOC 6 H 4 COO)] 2 O 2,(Id)表明,在固态ID中,不对称单元中有两个独特的中心对称二聚体。单个分子符合四有机锡氧烷结构,在考虑分子间锡与氧的紧密接触后,六价配位既分配给环内锡原子,又分配给环外锡原子。晶体为三斜晶,空间群为P,晶胞尺寸为a 13.503(3),b 24.226(4),c

atoms in solution. The crystalstructures of 1, 3 and 5 have been established by single crystal X-ray diffraction. The bonding in 1 differs from that in 3 but in both structures two different environments around the tin atoms are evident with the geometry around each tin atom being that of a distorted trigonal bipyramid with alkyl groups at the equatorial positions. The structure of 5 consists of chains
