HexacyanostannateIV

Hexacyanostannate(IV) refers to the chemical compounds containing the hexacyanostannate(IV) anion, [Sn(CN)6]2-. This anion is a complex ion where a central tin atom in the +4 oxidation state is coordinated to six cyanide ligands. It is structurally analogous to hexacyanoferrate(II), [Fe(CN)6]4-, and hexacyanoferrate(III), [Fe(CN)6]3-.

The hexacyanostannate(IV) anion is typically found as a salt with various cations. For instance, potassium hexacyanostannate(IV), K2[Sn(CN)6], is a known compound. These salts are generally stable under normal conditions. The tin in this complex is octahedrally coordinated by the carbon atoms of the cyanide ligands.

Hexacyanostannate(IV) compounds have applications in analytical chemistry. They can be used as reagents for the detection and determination of certain metal ions. For example, some hexacyanostannate(IV) salts can precipitate specific cations, allowing for their quantitative analysis. Research has also explored their potential use in materials science, such as in the development of novel coordination polymers or as precursors for tin-containing materials. The synthesis of hexacyanostannate(IV) compounds often involves the reaction of tin(IV) salts with cyanide sources under controlled conditions.
