synthesis and spectroscopic characterization are described of six-coordinated diorganotin(IV) complexes of the type RR′SnX2·L2 and RR′SnL′2 where RR′ = diphenyl, bis(p-tolyl), bis(m-chlorophenyl), bis(p-chlorophenyl), MeEt, Et(n-Pr); X Cl or NCS; L = neutral monodentate oxygen donor (containing , , or grouping) or bidentate donor (2,2′-bipyridyl, 4,4′-dimethyl-2,2′-bipyridyl, 1,10-phenanthroline or
合成和光谱表征的六配位二有机锡(IV)的类型RR'SnX的复合物描述的2 ·L 2和RR'SnL' 2,其中RR'=二苯基,双(p -甲苯基),双(米氯苯基),双(对氯苯基),MeEt,Et(n-Pr);XCl或NCS;L =中性单齿氧供体(包含,或成组)或双齿供体(2,2'-联吡啶,4,4'-二甲基-2,2'-联吡啶,1,10-菲咯啉或3,4,7, 8-四甲基-1,10-菲咯啉); L'= 8-喹啉基或2-甲基-8-喹啉基。光谱数据(特别是119m SnMössbauer)已用于推断[SnR 2这些复合物中的骨架,最近在一些情况下进行的X射线研究证实了这一点。结果表明,与锡连接的碳原子和杂原子供体配体中的取代基对六配位八面体络合物中反式或顺式-[SnR 2 ]构型的立体化学偏好具有强烈影响。
