The reaction of [Cp*IrCl 2 ] 2 with dilithium 1,2‐ ortho ‐carborane‐1,2‐diselenolate 3 leads to the green 16‐electron diselenolene complex [Cp*Ir{Se 2 C 2 (B 10 H 10 )}] ( 4 ) which takes up two‐electron ligands such as trimethylphosphane to give the 18‐electron diselenolate derivative [Cp*Ir(PMe 3 ){Se 2 C 2 (B 10 H 10 )}] ( 5 ). The molecular structures of 4 and 5 were determined by X‐ray crystal structure analysis. The 77 Se‐nuclear shielding in 4 is lower by almost 500 ppm relative to that in 5 .
