Complexes of the form [Ru3(μ‐H)(μ3‐C2X)(μ‐dppm)(CO)7] have been widely characterized structurally for diverse R = H, tBu, CMePh(OH), CPhCH2, C5H7, C5H6Me, C6F5, as well as being studied theoretically. The R = Ph derivative was found to be isotypic with its C6F5 analogue, presenting an unusual opportunity for a comparative structural study, both structures being (re‐)determined at ‘low’‐temperature, whereupon the unit cell of the Ph derivative was found to double. The structure of [AuRu3(μ‐C2C6F5)(CO)9(PPh3)] is also recorded.
