Chemistry:Trichlorostannate

From HandWiki

Trichlorostannate is the inorganic anion with the formula SnCl
3
. It is the chloride adduct of stannous chloride:

SnCl
2
+ Cl
→ SnCl
3

The trichlorostannate anion is pyramidal in shape, being similar to trichlorogermanate (GeCl
3
) and antimony trichloride.

The anion can be isolated as quaternary ammonium salt and cesium salts.[1] The compound with the formula K
2
SnCl

 · H2O
is a hydrated double salt, consisting of SnCl
3
and Cl

[Pt(SnCl3)5]3-. Color code: green = Cl, gray = Sn, blue = Pt.

Trichlorostannate serves as a ligand in coordination chemistry, illustrated by the complex [Pt(SnCl
