Lithium tungstate is the inorganic compound with the formula Li₂WO₄. It is a white solid that is soluble in water.

Structure

The salt consists of tetrahedrally coordinated Li and W centres bridged by oxides. The W-O and Li-O bond distances are 1.79 and 1.96 Å, respectively.^[1] The solid undergoes phase transitions at high pressures, such that the coordination geometry at tungsten becomes octahedral (six W-O bonds).
