Abstract

The complexes [(C5Me4R)TiF(µ-F)µ-O2P(OSiMe3)2]2 [R = Me (1), Et (2)] were prepared from [(C5Me4R)TiF3]2, (R = Me, Et) and OP(OSiMe3)3. The molecular structure of 2 has been determined by single-crystal X-ray diffraction analysis. An eight-membered Ti2O4P2 metallacycle bridged by two fluorine ligands between two titanium centers is observed.

摘要

配合物[(C5Me4R)TiF(µ-F)µ-O2P(OSiMe3)2]2 [R = 甲基 (1), 乙基 (2)] 由[(C5Me4R)TiF3]2(R = 甲基、乙基)和OP(OSiMe3)3制备而成。2的分子结构已通过单晶X射线衍射分析确定。观察到在两个钛中心之间由两个氟配体桥连的八元Ti2O4P2金属环。
