Rhodium gets a new flat cap : A novel face‐capping mode of toluene on the title {Os 3 Rh 4 } cluster is observed (see structure; Os blue, Rh green, C gray, O red, H white). The cluster is obtained from the reaction of [Os 3 Rh(μ‐H) 3 (CO) 12 ] with toluene in the presence of an excess amount of 4‐vinylphenol under reflux for 2 h. The new cluster has relatively short metal–metal bonds and an electron count of only 92, which is four electrons less than expected.
