Metatungstate Explained

In chemistry, metatungstate refers to the anion with the formula [W<sub>12</sub>O<sub>40</sub>]^8- and salts derived from this anion. The term also refers to protonated derivatives of this anion, including [H<sub>2</sub>W<sub>12</sub>O<sub>40</sub>]^6-. The unprotonated anion [W<sub>12</sub>O<sub>40</sub>]^8- has T_d symmetry.^[1]
