A novel heterobimetallic tantalum/iridium hydrido complex, [{Ta­(CH2 t Bu)3}­{IrH2(Cp*)}] 1, featuring a very short metal–metal bond, has been isolated through an original alkane elimination route from Ta­(CH t Bu)­(CH2 t Bu)3 and Cp*IrH4. This molecular precursor has been used to synthesize well-de...
