Hydrated lanthanoid(III) chlorides react with salts of dithiophosphinic acids in hot ethanolic solution to form the corresponding neutral tris or anionic tetrakis complexes, [Ln(S2PR2)3](R = C6H11) and [Ln(S2PR2)4]–(R = Me, OEt, or C6H11) respectively. The product of the reaction is sterically controlled. Displacement reactions with PPh3O to give mixed complexes are described. The characterisation, structures
水合镧系元素(III)的氯化物与二硫代次膦酸盐在热乙醇溶液中反应,形成相应的中性三或阴离子四环配合物[Ln(S 2 PR 2)3 ](R = C 6 H 11)和[Ln(S 2 PR 2)4 ] –(R = Me,OEt或C 6 H 11)。反应产物在空间上受到控制。PPh 3的置换反应描述了给出混合配合物的O。讨论了所有分离的配合物的表征,结构和光谱性质。将镧系元素-硫键与过渡金属-硫键进行比较
