Chapter 9 - Coordination compounds of nickel, palladium, and platinum

Abstract

This chapter addresses the photophysics and photochemistry of group 10 (Ni, Pd, Pt) metal complexes. The approach followed shows how reactivity arising from metal based electronic transitions hauls dependence from ligand environment modifications, with extensions in catalysis. Structure–reactivity patterns are reported under the prism of various spectroscopic results, including absorption and emission spectroscopy, electrochemistry, X-ray structure elucidation, and theoretical calculations. Initially, ligand field photophysics of complexes is presented, with main photochemical pathways realized via ligand field transitions. Traditional complexes are discussed and then the examination proceeds toward multidentate complexes bearing bidentate ligands such as diimines, dipyrrins, and dithiolene ligands, where charge transfer transitions mostly occur. The chapter reports contemporary aspects of photochemistry of group 10 metals, with applications in catalysis, materials, and medicinal chemistry.
