Abstract

original image

The face-capping carbene ligand displays a chairlike conformation and unusual side-on bonding in the triosmium cluster 1. This air-stable compound reacts in the presence of Lewis bases with atmospheric oxygen to form 2, in which the cyclohexadienone ligand is coordinated in a new mode to the Os3 framework.
