Germanium Tetrachloride

Title: Germanium Tetrachloride
CAS Registry Number: 10038-98-9
CAS Name: Tetrachlorogermane
Additional Names: germanium(IV) chloride
Molecular Formula: Cl4Ge
Molecular Weight: 214.45
Percent Composition: Cl 66.13%, Ge 33.87%
Line Formula: GeCl4
Literature References: Prepd from Ge and Cl2 or GeO2 and HCl: Bauer, Burschkies, Ber. 66, 277 (1933); Foster et al., Inorg. Synth. 2, 109 (1946).
Properties: Mobile liq. Fumes in air. Peculiar, acidic odor, but can be distinguished from that of concd HCl. Appreciably volatile at room temp. d2020 1.879. bp760 83.1°. mp -49.5°. Hydrolyzed by water with a crackling noise. Is stable, but not very sol in 6N HCl. If more concd HCl is used, the soly of GeCl4 is reduced. Sol in benzene, ether, other organic solvents.
