Photocondensation of mer-trichlorotris(diethyl sulphide)iridium(III)

Abstract

Photolysis of mer-[IrCl₃(SEt₂)₃](1) in benzene or toluene solution gives a mixture of di-µ-chloro-tetrachloro-tetrakis(diethyl sulphide)di-iridium(III)(2) and µ-chloro-pentachloro-µ(diethyl sulphide)-tris(diethyl sulphide)di-iridium(III)(3). The unusual bridging diethyl sulphide group in (3) is identified by the absence of rapid inversion at the sulphur atom.
