temperature leads to the cleavage of one Bi-C bond only, affording a 1D polymer [(Ph2Bi)(cycPO2)]n, ((1,1,2,3,3-pentamethyltrimethylene phosphinate is denoted as cycPO2) (2). Both the complexes were characterized by single crystal X-ray diffraction. In both complexes the phosphinate ligands are present in an anisobidentate (bridging) coordination mode.
图形摘要 摘要 Ph3Bi 与位阻次膦酸 1,1,2,3,3-五甲基三亚甲基次膦酸 cycP(O)OH·2H2O} 在两种不同温度下的反应,一种在回流条件下,另一种在室温,在四氢呋喃中进行了研究。在回流条件下,两个 Bi-C 键(BiPh3 的)断裂导致形成 16 元大环 [(PhBi)4(cycPO2)8] (1)。另一方面,室温下的反应导致仅一个 Bi-C 键断裂,得到一维聚合物 [(Ph2Bi)(cycPO2)]n, ((1,1,2,3,3-pentamethyltrimethylene phosphinate表示为 cycPO2) (2). 两种配合物均通过单晶 X 射线衍射表征。在这两种配合物中,次膦酸盐配体均以异双齿(桥接)配位模式存在。
