characteristisation of the 1:2 complexes [SnX 4 (R 2 E) 2 ] (R = C 6 H 5 CH 2 , Me 3 SiCH 2 ; E = S, Se; X = Cl, Br) and the 1:1 complexes [SnCl 4 (bmt)] (bmt = 3,4-bis(methylthio)-toluene and [SnCl 3 (C 6 H 5 )(dth)] (dth = 2,5-dithiahexane). Variable temperature 1 H NMR studies have confirmed the previously observed cis/trans isomerism about tin in the [SnX 4 L 2 ] complexes, and we have additionally
摘要我们报道了1:2配合物[SnX 4(R 2 E)2](R = C 6 H 5 CH 2,Me 3 SiCH 2; E = S,Se; X = Cl,Br)的制备和表征。和1:1配合物[SnCl 4(bmt)](bmt = 3,4-双(甲硫基)-甲苯和[SnCl 3(C 6 H 5)(dth)]](dth = 2,5-二硫代己烷)。可变温度1 H NMR研究已经证实了先前观察到的[SnX 4 L 2]络合物中锡的顺式/反式异构体,并且我们还发现在低温下停止了关于硫和硒的金字塔形原子反转的现象。其特征在于观察[SnX 4 L 2]配合物中的前手性中心以及螯合物中的dl和内消旋异构体的混合物。
