From conversions of Ar2SnH2 (Ar = Tripp, Dipp; Tripp = 2,4,6-Triisopropylphenyl, Dipp = 2,6-Diisopropylphenyl), and a bismuth(III) amide, Bi[N(SiMe3)2]3, we isolated the first representatives of mixed, uncharged Bi/Sn clusters, Bi8Sn3Ar6. Along with unprecedented bicyclo[2.2.0]hexanes, (HAr2Sn)2Sn2Bi4, these have been characterized by single crystal X-Ray diffraction, heteronuclear NMR, vibrational
来自 Ar 2 SnH 2 (Ar = Tripp, Dipp;Tripp = 2,4,6-三异丙基苯基,Dipp = 2,6-二异丙基苯基)和铋( III )酰胺Bi[N(SiMe 3 ) 2 ]的转化在图 3 中,我们分离出了混合的、不带电的 Bi/Sn 簇的第一个代表 Bi 8 Sn 3 Ar 6。随着前所未有的双环[2.2.0]己烷,(HAr 2 Sn) 2 Sn 2 Bi 4,这些已通过单晶 X 射线衍射、异核 NMR、振动和紫外-可见光谱表征。进行了量子化学计算以了解孤立的多面体化合物内的键合。
