acids, R 2 PO 2 H, where R = tert-butyl, benzyl, and cyclohexyl, has led to new types of structural forms for hexacoordinated tin: two cubic clusters; [n-BuSn(O)O 2 P(t-Bu) 2 ] 4 (1) and [n-BuSn(O)O 2 ,P(CH 2 Ph) 2 ] 4 (2), respectively, and a "butterfly" cluster, [n-BuSn(OH)(O 2 P(C 6 H 11 ) 2 ] 2 (3). Interesting transformations of cubes and the butterfly derivative yield oxygen-capped cluster formulations
正丁基锡酸与次膦酸 R 2 PO 2 H(其中 R = 叔丁基、苄基和环己基)的反应导致了六配位锡的新型结构形式:两个立方簇;[n-BuSn(O)O 2 P(t-Bu) 2 ] 4 (1) 和 [n-BuSn(O)O 2 ,P(CH 2 Ph) 2 ] 4 (2) 和一个“蝴蝶”簇,[n-BuSn(OH)(O 2 P(C 6 H 11 ) 2 ] 2 (3)。有趣的立方体变换和蝴蝶衍生物产生氧封端簇公式,[(R'Sn(OH) )O 2 PR 2 ) 3 O][R 2 PO 2 ],其中 R = n-Bu 和 R = C 6 H 11 或 CH 2 Ph. 119 Sn 和 31 P NMR 在溶液中显示了这些结构特征。119 Sn化学位移与簇复杂性的增加相关,即与迄今为止发现的各种配方中锡组分的配体增加相关。
