The 'P2N' mixed donor ligand 2-(diphenylphosphino)-N-[2- (diphenylphosphino)benzylidene]benzeneamine (PNCHP) reacts with [MCl 2(1,5-cyclooctadiene)] and [M(CH3)Cl(1,5-cyclooctadiene)] to give the complexes [M(PNCHP-κ3P,N,P)Cl]Cl (M=Pt or Pd) and [Pd(PNCHP-κ3P,N,P)(CH3)]Cl, respectively. The ionic chloride can be exchanged with BF4- by reaction with AgBF4. Abstraction of the covalent chloride with AgBF4 in the presence of acetonitrile yields [Pt(PNCHP-κ3P,N,P)(CH 3CN)]2+. The acetonitrile ligand of this dication can be substituted with a variety of ligands to afford complexes of the type, [Pt(PNCHP-κ3P,N,P)L]2+ (L=the monodentate ligands: triphenylphosphine, 2-picoline, 3-picoline or the chelate ligands: 1,10-phenanthroline, 2,2′-bipyridine, bis(diphenylphosphino) ethane, 2,2′:6′,2″-terpyridine). The latter ligands all bind in a bidentate fashion to give five-coordinate complexes. The compounds have been characterised by spectroscopic and analytical means. The single crystal structures of the four-coordinate complexes, [Pt(PNCHP-κ3P,N,P)Cl]Cl and [Pt(PNCHP-κ3P,N,P) (PPh3)](BF4)2, and the five-coordinate complexes, [Pt(PNCHP-κ3P,N,P)L](BF4)2 (L=1,10-phenanthroline and 2,2′:6′,2″- terpyridine), have been determined.
