Sodium paramolybdate revisited

Srinivasan, Bikshandarkoil R; Morajkar, Sudesh M

Abstract

The term paramolybdate refers to the species of formula [Mo7O24]6-. A convenient method for the rational synthesis of a sodium paramolybdate namely hexasodium heptamolybdate(VI) 14-hydrate Na6[Mo7O24]·14H2O and its spectral and thermal characterization are reported. Cyclic voltammetric and conductivity studies of an aqueous solution of Na6[Mo7O24]·14H2O reveal the presence of hydrated Na+ions and heptamolybdate anions in solution unlike a sodium coordinated heptamolybdate in the solid state.
