A quasi-covalent metal-metal bond in an early-late heterobimetallic Ti-Pt complex stabilized by phosphinoenolate ligands

Chem Commun (Camb). 2003 Mar 7:(5):610-1. doi: 10.1039/b211289m.

Abstract

An unusual early-late bimetallic complex with direct metal-metal bonding is obtained from a phosphinoenolate ligand-assisted reaction between Ti(IV) and Pt(0) reagents which occurs by formal insertion of the Pt(0) centre into a Ti(IV)-O bond; X-ray data and EHMO calculations indicate the presence of a quasi-covalent Ti(III)-Pt(I) bond (2.721(2) A).
