Mononuclear complexes of cyclodiphosphazane with an uncoordinated phosphorus centre [RuCl2(η6-cymene){l-κP}] (1a) (L = cis-{(o-MeOC6H4O)P(μ-NtBu)}2) and [PdCl2(PEt3){l-κP}] (1b) react with 1 equiv. of [AuCl(SMe2)] to afford RuII/AuI and PdII/AuI heterodinuclear complexes [RuCl2(η6-cymene){μ-l-κP,κP}AuCl] (2) and [PdCl2(PEt3){μ-l-κP,κP}AuCl] (3), respectively. Heterotrinuclear complexes [PdCl2{μ-l-κP,κP}2(AuCl)2] (4), [PtCl2{μ-l-κP,κP}2(AuCl)2] (5) and [CuI{μ-l-κP,κP}2(AuCl)2] (6) containing PdII/2AuI, PtII/2AuI and CuI/2AuI metal centers have been synthesized from the reactions of trans-[PdCl2{l-κP}2] (1c), cis-[PtCl2{l-κP}2] (1d) and [CuI{{l-κP}2] (1f) respectively, with 2 equiv. of [AuCl(SMe2)]. Molecular structures of complexes 2, 3 and 4 were established by single crystal X-ray diffraction studies.
Graphical abstractSelective monodentate coordination of the cyclodiphosphazane, cis-{(o-MeOC6H4O)P(μ-NtBu)}2 with metal precursors such as [RuCl2(η6-cymene)]2, [PdCl2(PEt3)]2 and [MCl2(COD)] (M = Pd, Pt) and bridging bidentate coordination with [AuCl(SMe2)] gives facile synthetic approach for RuII/AuI, PdII/AuI, PdII/2AuI, PtII/2AuI and CuI/2AuI heterometallic complexes.Figure optionsDownload full-size imageDownload as PowerPoint slide
