The structures of osmium carbonyl (hydride) clusters
The structures of osmium carbonyl clusters [Osx(CO)yHx]z-
This page lists the known structurally characterised osmium carbonyl clusters according to structure type, closo-, nido-, arachno- and hypho- and number of cluster vertices. Click on a molecular formula to bring up a page with the 3D structure of that cluster. Hydrogen atoms have not been located in every case.
