The ligand behaviour of N‐heterocyclic germylenes (NHGe) with respect to their σ‐donor ability, π‐acceptor strength and net electron donating ability is determined by calculating their molecular electrostatic potential (MEP). Correlation of the MEP to the Tolman Electronic Parameter (TEP) is achieved using a family of phosphite ligands. The results indicate that the π‐acceptor strength of NHGe reaches significantly beyond that of phosphites. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2006)
