Not only CO, NO, and related molecules but also stibanes SbR 3 can act as bridging ligands in dinuclear complexes. Compound 2 , the first compound of this type, which is a accessible upon thermolysis of 1 and characterized by X‐ray structure analysis, is remarkably stable. The Sb i Pr 3 ligand is easily displaced by stibanes SbR 3 containing smaller substituents R (Me, Et) and also by CN t Bu without disturbing the carbene bridges.
