Abstract

Reaction of (NBu4)(2)[Mo2O7] with [Cu(CH3CN)(4)](PF6) in acetonitrile results in isolation of the orange beta-octamolybdate [Cu(CH3CN)(4)](2)[Mo8O26Cu2(CH3CN)(4)] (1) along with the colourless alpha-octamolybdate [Cu(CH3CN)(4)](4)[Mo8O26]center dot 2CH(3)CN (2). Both products decompose rapidly upon removal from their mother liquors, forming an insoluble, dark brown coloured phase with the composition Cu-4[Mo8O26]center dot 0.6CH(3)CN center dot 16H(2)O (3). The copper(I) acetonitrile derivatised isopolyanion in 1 thus represents an intermediate structure between the simple, underivatised octamolybdate 2 and fully condensed, polymeric phase 3.
