Seven organo-bridged bis[tris(arylchalcogenolato)tin] compounds with the general formulae (R′E)3Sn–R–Sn(ER′)3 (R = –(CH2)4–, 1,4-bis(methyl)benzene, 4,4′-bis(methyl)biphenyl; R′ = Ph, 1-Np, 2-Np; E = S, Se) were synthesized and characterized by means of X-ray diffractometry as well as NMR spectroscopy. Three different conformations of the arylchalcogenolato groups ER′ with respect to the bridging group
具有通式 (R'E)3Sn–R–Sn(ER')3 (R = –(CH2)4–, 1,4-bis(methyl)) 的七种有机桥连双[三(芳基硫属元素)锡]化合物苯,4,4'-双(甲基)联苯;R' = Ph, 1-Np, 2-Np; E = S, Se) 合成并通过 X 射线衍射和核磁共振光谱表征。通过量子化学研究合理化和解释了芳基硫属化合物基团 ER' 相对于桥接基团 R 的三种不同构象。
