Iridium-Molybdenum Carbido Complex via C-Se Activation of a Selenocarbonyl Ligand:(μ-Se 2 )[Ir 2 {C≡Mo(CO) 2 (Tp*)} 2 (CO) 2 (PPh 3 ) 2 ] (Tp*= hydrotris(dimethylpyrazolyl)borate)

Abstract

The reaction of [Et4N][Mo(CSe)(CO)2(Tp*))] (Tp* = hydrotris(dimethylpyrazolyl)borate) with [Ir(NCMe) (CO) (PPh 3)2]BF4 results not in the anticipated isoselenocarbonyl complex [(Tp*) (CO)2Mo-CSe-Ir(CO) (PPh 3)2] but rather in the tetranuclear bis(μ-carbi
