An attractive route to mixed‐valent metal oxides has been developed from the observation that on slow heating 1 completely loses its acetonitrile ligands at temperatures below 350 °C and is transformed into an oxide containing Mo VI and Re in two oxidation states. Salt 1 is prepared surprisingly simply according to Equation (a) and shows unexpected electron‐acceptor properties, which makes it a potential source of a naked Re 2 4+ion. The structural parameters of the cation of 1 point to a ReRe triple bond, although no strong α or π donors stabilize the system.
