The preparation and structure of [W(CO)4(η3-Te3)][SbF6]2 containing the first three-membered chalcogen ring
Abstract
The reaction of Te4(SbF6)2 with W(CO)6 in SO2–AsF3 produces [W(CO)4(η3-Te3)][SbF6]2(1), which contains a three-membered tellurium ring co-ordinated in π fashion to the tungsten carbonyl fragment.
