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

SnCl₂ + 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 K₂SnCl₄·H₂O is a hydrated double salt, consisting of SnCl−3 and Cl⁻.^[2]

Trichlorostannate serves as a ligand in coordination chemistry, illustrated by the complex [Pt(SnCl₃)₅]³⁻.^[3]
