The reaction of Cp{sup *}Ir({eta}{sup 4}-2,5-Me{sub 2}T), where {eta}{sup 4}-2,5-Me{sub 2}T is 2,5-dimethylthiophene coordinated through the four ring carbons, with Cp(CO){sub 2}Mo{triple bond}Mo(CO){sub 2}Cp gives ({eta}{sup 4},S-{mu}{sub 3}-2,5-Me{sub 2}T)(IrCp{sup *})(Mo(CO){sub 2}Cp){sub 2}, in which the bridging thiophene is {eta}{sup 4}-coordinated to the Ir and bonded via the sulfur to both Mo atoms. The same product is obtained from the ring-opened isomer of Cp{sup *}Ir(2,5-Me{sub 2}T). The structure of the product, which is the first example of a thiophene coordinated to three metal centers, was established by X-ray crystallography.
