The coordination behaviour of a variety of amine containing phosphine ligands has been studied. Two new multifunctionalised ligands have been prepared and shown along with three known ligands to favour a variety of coordination modes when complexed with rhodium(III) centres. The hemilabile PN chelate ligands show three different types of behaviour: strong P,N chelation even in the presence of chloride ions, strong P,N chelation after a chloride ligand is removed (Ag salts), and weak coordination after chloride abstraction. Five of the complexes have been characterised by X-ray crystallography. Multinuclear NMR and IR spectroscopies were also highly diagnostic in assigning the coordination chemistry favoured by each ligand.
Synthesis, structure and properties of new pyridylaminophosphine complexes

Reaction of diphenylphosphino-2-aminopyridine with a variety of late transition metal species eg Pt (II), Pd (II), Ru (II) and Rh (III) in most cases leads to five-membered metallocycles containing M-P-N(H)-C-N rings. Treatment of these species with base results in deprotonation of the amino group, formation of a neutral species and election delocalisation over the P-N bond.
