2-(Diphenylphosphinoamino)pyridine, dppap [Ph2PNHpy], and over 40 illustrative examples of its complexes have been prepared. Monodentate, bidentate and bridging co-ordination of the neutral (and bidentate deprotonated ligand) has been demonstrated in a range of palladium, platinum and gold complexes. Ten demonstrative examples have been characterised by single crystal X-ray diffraction. Ph2PNHpy exists as hydrogen-bonded dimer pairs; cis[PtCl(Ph2PNHpy-P,Ar){Ph2PNHpy-P}]Cl packs in hydrogen-bonded infinite chains; cis-[PtCPh2PNpy-.P.A2] and cis-[Pd(Ph2PNpy-P,N)2] are isomorphous. The structures of cis-[Pd(Ph2PNHpy-P,N)2][BF4]2, [AuCl(Ph2PNHpy-.P)], [Pt(C8H12OMe)(Ph2PNpy-P,N)]-H2O illustrating hydrogen-bonding, cis-[PtCl(Ph2PNHpy-P,N)(PMe3)]Cl, cis[PtCl(Ph2PNpy-P,N(PMe3)] and cis-[PtCl(Ph2PNHpy-P,N)(P(OPh)3)]Cl are also reported.

The new polydentate ligands 2-(diphenylphosphinoamino)pyridine (PAP), 2-(diphenylphosphinoamino)-4-methylpyridine (4PAP), and 2-(diphenylphosphinoamino)-6-methylpyridine (6PAP) and their thio and seleno derivatives have been synthesized and characterized. Coordination complexes of 4PAP and 6PAP have been isolated, viz., (a) 1:1 metal-ligand complexes MLCl2: (i) M = Co(II), Ni(II), Hg(II), Pd(II), L = 4PAP; (ii) M = Co(II), Ni(II), Pd(II), L = 6PAP; (b) 1:2 metal-ligand complexes, ML2X2·nH2O: Co(4PAP)2Cl2, Ni(4PAP)2Cl2·2H2O, [Ni(4PAP)2](ClO4)2·2H2O, Hg(4PAP)Cl2, Ag(4PAP)2NO3, [Ni(6PAP)2](ClO4)2; (c) [Ni(4PAP)2X](ClO4), X = Cl, Br; (d) 1:3 metal-ligand complexes ML3X2: [Ni(4PAP)3](ClO4)2. Physicochemical studies, including the measurement of conductivity, magnetic moment, solution molecular weight, and infrared, visible, and nuclear magnetic resonance absorption spectra, were performed on the complexes of Co(II) and Ni(II); their structures are discussed.
