Formation of Ir-Rh and Ir-Mo bonds by using an ancillary ortho-carborane-1,2-diselenolato ligand

Abstract

Trinuclear clusters containing heteronuclear Ir-M bonds, for example [{Cp*Ir[Se2C2(B10H10)]} 2Rh] (1), were obtained from the reactions of the 16-electron complex [Cp*Ir{Se2C2(B10H10)}] and characterized by X-ray crystallography. Compound 1 is thermally converted into 2 by generation of an additional Ir-B bond (see picture: Ir yellow; Rh red; Se magenta; C black; B white). Cp* = η5-C5Me 5.
