Reaction of (NBu4)2[Mo2O7] with [Cu(CH3CN)4](PF6) in acetonitrile results in isolation of the orange β-octamolybdate [Cu(CH3CN)4]2[Mo8O26Cu2(CH3CN)4] (1) along with the colourless α-octamolybdate [Cu(CH3CN)4]4[Mo8O26]·2CH3CN (2). Both products decompose rapidly upon removal from their mother liquors, forming an insoluble, dark brown coloured phase with the composition Cu4[Mo8O26]·0.6CH3CN·16H2O (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.
