Trichlorogermanate is the inorganic anion with the formula GeCl−3. It is the chloride adduct of germanium dichloride:

GeCl2 + Cl− → GeCl−3

The anion can be isolated as a quaternary ammonium salt. [1] The anion is similar to trichlorostannate (SnCl−3).

The anion is pyramidal according to X-ray crystallography with Cl-Ge-Cl angle of about 95° and Ge-Cl distance of 232 pm. [2]
