The CO valence vibrations and short GeII–Mo bonds in fac-[(NHGe)3Mo(CO)3] and [Ni(NHGe)4], both of which contain N-heterocyclic germylene ligands, indicate the weak donor and good π-acceptor properties of these ligands, in line with quantum chemical studies and their PES orbital ionization potentials. The ligand bending in the complexes may be due to packing effects.
