As with gold, relativistic effects are important in the chemistry of mercury. Together with the closed‐shell d 10 configuration of Hg 2+ they account for the special bonding schemes as preferred linear coordination with highly covalent contributions to chemical bonding or special affinities to nitrogen and sulfur that are so prominent in mercuric chemistry. This research report summarizes recent research on coordination compounds with halogen, oxygen and, especially, nitrogen as direct bonding partners of divalent mercury and their competition with each other. In a rather systematic way N‐donor ligands with one, two and more than two nitrogen atoms have been inspected in order to elucidate the influences that lead to the special bonding schemes of Hg II ‐N compounds.
