Dimethyltin dihalides Me2SnX2 (X = Cl, Br) only form 1:1 complexes with 2,6-dimethoxyphenylphosphine oxides Φ3PO, PhΦ2PO and Ph2ΦPO (Φ = 2,6-(MeO)2C6H3) even though the ligands are used in excess. 2,6-Dimethoxyphenylphosphine sulphides Φ3PS and PhΦ2PS also form analogous 1:1 complexes, while Ph2ΦPS and Ph3PS do not react. X-Ray crystal structural analysis of Me2SnCl2·OPΦ3 reveals that the tin
二甲基二卤化物我2 SNX 2(X =氯,溴)仅形成1:1种的复合物与2,6- dimethoxyphenylphosphine氧化物Φ 3 PO,PhΦ 2 PO且Ph 2 ΦPO(Φ= 2,6- (MeO)2 C 6 H 3),即使配体过量使用。2,6- Dimethoxyphenylphosphine硫化物Φ 3 PS和PhΦ 2 PS也形成类似的1:1种的复合物,而博士2 ΦPS且Ph 3个PS不反应。我的X射线晶体结构分析2的SnCl 2 ·OPΦ 3揭示了锡原子是五配位的一个扭曲的三角双锥布置中,与氯和在赤道位置的两个甲基碳原子和其他氯和Φ 3的轴向位置PO氧原子。
