Amine-substituted α-N(standard)- and δ-N(remote)-pyridylidene complexes: Synthesis and bonding

► New examples of normal and remote carbene complexes of Ni(II) and Pd(II) prepared. ► First examples of pyridylidene complexes in which metal fragments and amino substituents exchange places. ► Crystal structure determinations indicate predominant pi-donor effects of the amine-substituent independent of its position. ► Valuable bonding information gathered from NMR studies.
