The heaviest CO‐homologous ligand {µ‐PbSe} for transition metals is coordinated to a trigonal bipyramidal {Rh 3 Se 2 }‐based cluster, as reported by S. Dehnen et al. in their Communication on page 11283 ff. A bent coordination mode for {µ‐PbSe} is favored over both planar Rh(µ‐PbSe)Rh coordination and bridging by CO as a result of the size and the energetic order of the larger ligand′s molecular orbitals, which fit better with the steric demands of the cluster than those of CO.
