Towards f and d electron interactions in amido metal complexes

A short review of heterobimetallic amido complexes incorporating lanthanides and Group 9 or 10 metals is given. The use of bisaminopyridinato ligands allows the isolation of compounds with very short metal-metal distances. The reaction of bisaminopyridnato 'ate'-complexes with late transition metal chlorides gives rise to such complexes if the ligand transfer from the lanthanide center to the late transition metal can be avoided.
