0Explain the structures of different types of silicates. (nceret)
- A silicate contains an anionic si compound. The great majority of the silicates are oxides, ([SiF6]2−) and other anions are also included.
- "orthosilicates" is the anion SiO4−
- 4 or its compounds. Related to orthosilicate are families of anions (and their compounds) with the formula [SiO2+n]2n−. Important members are the cyclic and single chain silicates {[SiO3]2−}n and the sheet-forming silicates {[SiO2.5]−}n.
