In chemistry, the term stannate or tinnate refers to compounds of tin (Sn). Stannic acid (Sn(OH)4), the formal precursor to stannates, does not exist and is actually a hydrate of SnO2. The term is also used in naming conventions as a suffix; for example the hexachlorostannate ion is .
In materials science, two kinds of tin oxyanions are distinguished: orthostannates contain discrete units (e.g. K4SnO4) or have a spinel structure (e.g. Mg2SnO4) metastannates with a stoichiometry MIISnO3, MSnO3 which may contain polymeric anions or may be sometimes better described as mixed oxides
