Di- and tetra-nuclear complexes with bis(diphenylphosphino)amide and bis(diphenylphosphino)methanide as bi- and tri-dentate ligands. X-Ray structures of [(Ph3P)(O3ClO)AgN(Ph2PAuPPh2)2NAg(OClO3)(PPh3)] and [(C6F5)AuCH(Ph2PAuPPh2)2ChAu(C6F5)]

Abstract

Deprotonation of bis(diphenylphosphino)amine or bis(diphenylphosphino)methane with [AuCl(CH₂PR₃)] leads to neutral complexes [X(Ph₂PAuPPh₂)₂X](X = N or CH) that react further with [Au(C₆F₅)(tht)](tht = tetrahydrothiophene) or [Ag(OClO₃)(PPh₃)], giving neutral tetranuclear derivatives, ring systems in which the amido or methanido ligands are tridentate (confirmed by X-ray structures of two products).
