Abstract

A series of phospho-polyoxotungstate anions was transferred to the gas phase via electrospray ionization (ESI), and the anions fragmentation was examined by collision-induced dissociation (CID). The anions included [PW(12)O(40)](3-), [P(2)W(18)O(62)](6-), and [Co(4)(H(2)O)(2)][PW(9)O(34)](2) (10-) as well as lacunary and metal-substituted derivatives such as [PW(11)O(39)](7-) and [MPW(11)O(39)](5-) (M = Co(II), Ni(II), Cu(II)). Common species observed in the mass spectra arose from protonation and alkali metal cationization of the precursor ions. Additional species arising from the formal loss of oxide from the precursor species were also observed, presumably formed via protonation and the loss of an oxo ligand as water.
