Metasilicate

Idealized structure of sodium metasilicate.

Metasilicates are silicates containing ions of empirical formula SiO2−
3. Common stoichiometries include MI
2SiO3 and MII
SiO3. Metasilicates can be cyclic, usually the hexamer (SiO3)12−6 or chains (SiO
3)2−
n.

Common compounds containing metasilicate anion are:

Pyroxene (diopside) is a mineral classified as a metasilicate.
