This chapter outlines the chemistry of transition metal complexes with amide (–NR2) and phosphide (–PR2) ligands. Such species may be considered as metalla-amines and -phosphines: the Group 15 atom in the complex still possesses a reactive lone pair of electrons, which may be used to form multiple bonds to the metal via π overlap with suitable vacant metal orbitals. The N or P atom thus acts as an intramolecular Lewis base. Bridging structures resulting in multinuclear complexes are also found. Synthesis and reactivity patterns of amide and phosphide complexes are addressed in detail. In addition to the MPR2-type species noted above, phosphorus exhibits complexes in which it is pentavalent.
