The tetrachloride is a colorless, thin liquid of specific gravity 1.887 at 18.0° as measured by P. Mann. It does not solidify at -20°. Its boiling point is around 80° . . . From its composition GeCl4 and its specific gravity, its (molecular) volume is calculated as 113.3; Mendeleev prognosticated the specific gravity of EsCl4 to be about 1.9, the volume 113, the boiling point probably a little below 100°.
