Transition Metal Complexes Containing Bidentate Phosphine Ligands

TLDR: In this paper, several transition metal complexes containing bidentate phosphine ligands are described, and a major complication in diphosphine complexes is the relative complexity of the ligands.

Abstract: Publisher Summary This chapter describes several transition metal complexes containing bidentate phosphine ligands. The bonding in metal–phosphine ligands due to the formation of π-type bonds between the metal and phosphorus atoms. Several techniques are used to study metal–phosphine complexes. These techniques include mass spectroscopy infrared spectroscopy, nuclear magnetic resonance, electronic spectroscopy, electron spin resonance, and Mossbauer spectroscopy. A major complication in diphosphine complexes is the relative complexity of the ligands. When a diphosphine complexes with a metal ion, the electron density on the phosphorus atom changes, and the ligand is restricted in the conformation it can assume. Thus the vibrational spectra of the free and coordinated ligands differ.
