Structural Aspects of Monomeric Platinum Coordination Complexes
ABSTRACT
This review covers structural parameters of almost two thousand monomeric Pt coordination complexes. The Pt is found in the oxidation states zero, +1, +2, +3 and +4, from which oxidation state +2 by far prevails. There is a wide variety of donor atom ligands from uni-, bi-, ter- and tetradentate with over seventeen types of donor atoms, from which by far prevails P and N donor ligands and chlorine atom. The Pt(0) atoms are two-, three- and four-coordinated; Pt(I) and Pt(III) are only four-coordinated, Pt(II) are four- and five-coordinated, and Pt(IV) are five- and six-coor-dinated. About 10% of these complexes exist as isomers. Included are distortion (65%), cis-trans (30%), mixed isomers and ligand isomerism. The structural parameters are discussed in terms of the coordination about the platinum atom, and correlations are drawn between donor atom, bond length and interbond angles with attention to any trans-effect.
