Novel dinuclear iridium(I) and mixed iridium(I)-rhodium(I) complexes. X-Ray crystal structure of di-µ-benzenethiolato-bis[dicarbonyliridium(I)]

Abstract

The thiolato-bridged iridium(I) carbonyl complexes [{Ir(SR)(CO)₂}₂](R = Bu^t or Ph) have been prepared by the reaction of [{Ir(SR)(C₈H₁₂)}₂] in pentane with CO, and the crystal structure of [{Ir(SPh)(CO)₂}₂] suggests the existence of intra- and inter-molecular metal–metal interactions; similar mixed iridium(I)–rhodium(I) chloro-bridged complexes have also been prepared.
