摘要：

In the solid state, the tungstate [NMe3(CH2Ph)]2[WO4].H2O contains chains of alternating [WO4]2- anions and water molecules linked by W=O...H-O-H hydrogen bonding; in organic solvents, oxo-alkoxo ligand exchange occurs readily between Q2WO4 (Q+ = NBun4+ or [NMe3(CH2Ph)]+) and [{WO(OMe4)}2] to produce the new binuclear oxoalkoxo-tungstate [W2O5)(OMe)4]2-, which is a precursor for non-aqueous polyoxo-tungstate synthesis.
