Zusammenfassung: | The ability of 3‐(diphenylphosphinomethyl)‐benzene‐1,2‐dithiol (pbdtH2) to act as ditopic ligand was probed in reactions with selected group‐10‐metal complexes. Reactions with [(cod)PdCl2] afforded a mixture of products identified as [Pd(pbdtH)2], [Pd2(μ2‐pbdt)2] and [Pd3(μ2‐pbdt)2Cl2]. The polynuclear complexes could be isolated after suitably adjusting the reaction conditions, and heating of a mixture in a microwave reactor effected partial conversion into a further complex [Pd3(μ2‐pbdt)3]. Reaction of pbdtH2 with [Ni(H2O)6Cl2] gave rise to a complex [Ni2(μ2‐pbdt)2], which was shown to undergo two reversible 1e-‐reduction steps. Reaction of [Pd(pbdtH)2] with [Au(PPh3)Cl] afforded heterotrinuclear [PdAu2(μ2‐pbdt)2(PPh3)]. All complexes were characterized by analytical, spectroscopic and single‐crystal X‐ray diffraction studies. Their molecular structures confirm the ability of the pbdt2- unit to support simultaneous P,S‐ and S,S‐chelating coordination to two metal centers. |
