Titanium Complexes with Tripodal Amido Ligands: Building Blocks for Stable Bimetallic Coordination Compounds Containing Highly Polar Metal–Metal Bonds

Abstract

Unsupported TiFe, TiRu, and TiCo bonds are found in the stable dinuclear compounds of type 1 (M = Fe, Ru, Co). These compounds were synthesized from the appropriate mononuclear titanium bromide complex and carbonyl metalates. The polydentate ligands on the early transition metal clearly provide the key to successful stabilization of the unsupported metal–metal bond.
