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,N)Ph2PNHpy-P}]Cl packs in hydrogen-bonded infinite chains; cis-[Pt(Ph2PNpy-P,N)2] 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.
2-(二苯膦氨基)吡啶,dppap [Ph2PNHpy],以及超过40个示例性的其配合物已被制备。在一系列钯、铂和金配合物中,示例了中性(以及双齿去质子化配体)的单齿、双齿和桥联配位方式。十个示范性例子通过单晶X射线衍射进行了表征。Ph2PNHpy以氢键结合的二聚体对形式存在;cis-[PtCl(Ph2PNHpy-P,N)Ph2PNHpy-P}]Cl通过氢键形成无限链;cis-[Pt(Ph2PNpy-P,N)2]和cis-[Pd(Ph2PNpy-P,N)2]是同构的。cis-[Pd(Ph2PNHpy-P,N)2][BF4]2、[AuCl(Ph2PNHpy-P)]、[Pt(C8H12OMe)(Ph2PNpy-P,N)]·H2O展示了氢键结合,cis-[PtCl(Ph2PNHpy-P,N)(PMe3)]Cl、cis-[PtCl(Ph2PNpy-P,N)(PMe3)]和cis-[PtCl(Ph2PNHpy-P,N)(P(OPh)3)]Cl的结构也被报道。
