Stannate
In chemistry the term stannate refers to compounds of tin (Sn). Stannic acid (Sn(OH)), the formal precursor to stannates, does not exist and is actually a hydrate of SnO. The term is also used in naming conventions as a suffix for example the hexachlorostannate ion is SnCl.
In materials science, two kinds of tin oxyanions are distinguished:
- orthostannates contain discrete units (e.g. KSnO) or have a spinel structure (e.g. MgSnO)
- metastannates with a stoichiometry MSnO, MSnO which may contain polymeric anions or may be sometimes better described as mixed oxides
These materials are semiconductors.
