摘要：

A novel voltammetrically active isopolyoxotungstate anion, [H6W18O60](6-) was prepared as a tetrapropylammonium (n-Pr4N+) salt from a freshly prepared solution (pH 4.0) of 500 mM (M = mol dm(-3)) W(VI) at ambient temperature. The [H6W18O60](6-) complex was obtained as a transient intermediate in the transformation of [W10O32](4-) into alpha-[H2W12O40](6-), and the formation conditions were elucidated in relation to those of [W10O32](4-) and alpha-[H2W12O40](6-). The [H6W18O60](6-) complex was characterized by W-183 NMR and voltammetric behaviors. (C) 2001 Elsevier Science B.V. All rights reserved.
