Rational synthesis of trinuclear (WIr2) cluster from the 16-electron half-sandwich complex Cp*Ir[Se2C2(B10H10)]

A trinuclear(WIr2) heterometallic complex [Cp*IrSe2C2B10H10]2W(CO)23 containing M-M bonding were obtained from the reaction of 16-electron complex Cp*IrSe2C2B10H10 with [W(CO)3(py)3], and its structure has been determined by X-ray crystallography.
