Properties: Thermally unstable gas at room temp; begins to dec into fluorine and oxygen at -100°. Pale yellow solid or yellow liq at low temp. mp -154°C (119 K). Early prepns, described as brown gas, red liq and orange solid (mp -163.5°), probably contained other fluorine-oxygen compounds as impurities: Goetschel et al., loc. cit. Strong oxidizing and fluorinating agent.
