Formation of IrRh and IrMo Bonds by Using an Ancillary ortho‐Carborane‐1,2‐diselenolato Ligand

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-C5Me5.
