Title: Germanium Tetrafluoride
CAS Registry Number: 7783-58-6
Molecular Formula: F4Ge
Molecular Weight: 148.63
Percent Composition: F 51.13%, Ge 48.87%
Line Formula: GeF4
Literature References: Prepd by heating BaGeF6 to around 700°: Dennis, Laubengayer, Z. Phys. Chem. 130, 520 (1927); Dennis, Z. Anorg. Allg. Chem. 174, 119 (1928); Biltz, ibid. 207, 65 (1932); Hoffman, Gutowsky, Inorg. Synth. 4, 147 (1953).
Properties: Colorless gas. Odor of garlic. Thermally stable up to about 1000°. d0 (liq) 2.162; d (solid; -195°) 3.148. mp -15° (under 3032 mm pressure). Sublimes at -36.5°. On contact with water, hydrolyzes to GeO2 and H2GeF6. Does not attack glass when absolutely dry. Corrodes mercury, grease.
Melting point: mp -15° (under 3032 mm pressure)
Density: d0 (liq) 2.162; d (solid; -195°) 3.148
 
Derivative Type: Trihydrate
