SbMesnPh3−n (n = 3 (1), 2 (2), 1 (3)) produces the 1:1adducts [AuCl(SbMesnPh3−n)] (n = 3 (4), 2 (5), 1 (6)), with a Sb−Au−Cl environment, regardless of the molar ratio used (1:1 to 1:4). Addition of the same stibines to [Au(tht)2]ClO4 (molar ratio 1:1 to 1:4) results in isolation of the 1:2adducts [Au(SbMesnPh3−n)2]ClO4 (n = 3 (7), 2 (10)), containing linear Sb−Au−Sb fragments, or the 1:3 adduct [Au(SbMesPh2)3]ClO4
[AuCl(tht)](tht =四氢噻吩)与SbMes n Ph 3- n(n = 3(1),2(2),1(3))的反应生成1:1的加合物[AuCl(SbMes n Ph 3-(n)](n = 3(4),2(5),1(6)),在Sb-Au-Cl环境下,无论使用的摩尔比(1:1至1:4)。向[Au(tht)2 ] ClO 4(摩尔比1:1至1:4)中添加相同的stibines可分离出1:2加合物[Au(SbMes n Ph 3- n)2] ClO 4(n = 3(7),2(10)),包含线性Sb-Au-Sb片段,或1:3加合物[Au(SbMesPh 2)3 ] ClO 4(11),具有准三角形状平面AuSb 3芯。当[Au(tht)2 ] CF 3 SO 3与1反应时,或在用AgSbF 6处理4时遵循重排过程,即[Au(SbMes 3)2 ] X( X = CF 3 SO 3(8),SbF
