Reaction of Ph₂PCH₂OH and {RP(S)(μ-S)}₂ (R = p-C₆H₄OMe, Lawesson's reagent), in toluene, gave the new hybrid P^III/P^V ligand Ph₂PCH₂OP(S)(R)SH 1 in high yield. Unfortunately, attempts to crystallise 1 gave, instead, suitable X-ray quality crystals of the Zwitterion Ph₂P⁺(CH₂OH)CH₂OP(S)(R)S⁻ 1′, presumably arising from the presence of some residual formaldehyde. Three homodinuclear complexes [Ru₂(η⁶-p-CH₃C₆H₄ⁱPr)₂{μ-Ph₂PCH₂OP(S)(R)S}Cl₃] (2) and [M₂(η⁵-C₅(CH₃)₅)₂{μ-Ph₂PCH₂OP(S)(R)S}Cl₃] [M = Rh, 3; M = Ir, 4 (R = p-C₆H₄OCH₃)] were obtained upon reaction of a 1:1 molar ratio of 1 and either [(η⁶-p-CH₃C₆H₄ⁱPr)RuCl(μ-Cl)]₂ or [M(μ-Cl)(Cl)(η⁵-C₅(CH₃)₅)₂]₂ (M = Rh and Ir), respectively. The mononuclear Ir^III complex Ir(η⁵-C₅(CH₃)₅)(Ph₂PCH₂OH)Cl₂ 5 was prepared for comparative spectroscopic and crystallographic purposes with 4. All compounds were characterised by a combination of multinuclear NMR and FT−IR spectroscopy and elemental analysis. In addition, the first example of a phosphine-dithiophosphonate ligand 1′ along with two homodinuclear complexes 2·CHCl₃ and 4 were determined by single crystal X-ray diffraction. Compound 5 displays an intramolecular O(1)−H(1)···Cl(2) hydrogen bond to a terminal Ir^III bound chloride ligand.

Ph ₂ PCH ₂ OH与{RP（S）（μ-S）} ₂（R =  p -C ₆ H ₄ OMe，Lawesson试剂）在甲苯中的反应，得到了新的杂化P ^{III /} P ^V配体Ph ₂ PCH ₂ OP（S）（R）SH 1高收率。不幸的是，尝试结晶1却获得了两性离子Ph ₂ P ⁺（CH ₂ OH）CH ₂ OP（S）（R）S ^- 1的合适的X射线质量的晶体′，大概是由于一些残留甲醛的存在引起的。三个同双核配合物的[Ru ₂（η ⁶ - p -CH ₃ Ç ₆ ħ ₄^我PR）₂ {μ-PH ₂ PCH ₂ OP（S）（R）S}氯₃ ]（2）和[M ₂（η ⁵ -C ₅（CH ₃）₅）₂ {μ-PH ₂ PCH ₂ OP（S）（R）S}氯₃ ] [M = RH，3 ; M = Ir，4（R =  p -C₆ ħ ₄ OCH ₃的1摩尔比）]在一个1的反应制得1和任一[（η ⁶ - p -CH ₃ Ç ₆ ħ ₄^我PR）的RuClμ-Cl）的]（₂或[M（ μ-Cl）的（氯）（η ⁵ -C ₅（CH ₃）₅）₂〕₂分别（M = Rh和Ir）的。该单核铱^III复杂的Ir（η ⁵ -C ₅（CH ₃）₅）（PH ₂ PCH ₂ OH）氯₂ 5与4制备用于比较光谱和晶体学目的。所有化合物都通过多核NMR和FT-IR光谱法以及元素分析相结合来表征。此外，通过单晶X射线衍射确定了膦-二硫代膦酸酯配体1 '以及两个同核复合物2 ·CHCl ₃和4的第一实例。化合物5显示分子内O（1）-H（1）··Cl（2）氢键与末端Ir ^III键合的氯化物配体。
