钼簇合物的簇解反应和两个多钼酸盐化合物的晶体结构

The Disintegration Reaction of the Trimolybdenum Cluster Compounds and Crystal Structure of Two Polymolybdate Compounds

含μ-Cl桥的三核钼簇阴离子[Mo_3(μ_3-O)(μ-Cl)_3(μ-OAc)_3Cl_3]-在Fe^(3+)作用下发生簇解反应,形成钼同多酸盐[FeCl(DMF)_5][Mo_6O_(19)](1)。在合成[Mo_3(μ-S_2)(μ-S_2)_3(dtp)_3Cl]簇合物的反应中如果有CaI存在,则形成钼磷杂多酸盐(Et_4N)_4[PMo_(12)O_(40)](DMF)_2(2)。本文报道这两个多钼酸盐化合物的晶体结构,并讨论有关的簇解反应。

The reaotion of the trimolybdenum cluster anion [Mo_3 (μ_3-O) (μ_3-Cl)_3(μ-OAc)_3Cl_3]^- with Fe(Ⅲ)results in the disintegration of [Mo_3(μ_3-O)(μ-Cl)_3] core to form the isopolymolybdate oompound [FeCl(DMF)_5] [Mo_6O_(19)] (1) and if CuI is employed in the synthetic reaction for the preparation of [Me_3 (μ_3-S)(μ-S_2)_3(dtp)_3Cl], a heteropolymolyb-date compound [(Et_4N)_4(PMo_(12)O_(40))] (DMF)_2(2) is obtained. The crystal structure of 1 and 2 have been established by X-ray diffraction study. The related disintegration reactions are discussed.
