[30] [31] [32] Despite this controversy, many properties of diatomic astatine have been predicted; [33] for example, its bond length would be 300 ± 10 pm, dissociation energy < 50 kJ/mol, [34] and heat of vaporization (∆H vap) 54.39 kJ/mol. [35] Many values have been predicted for the melting and boiling points of astatine, but only for At 2 ...

Chlorine trifluoride has a boiling point of −12 °C. Bromine trifluoride has a boiling point of 127 °C and is a liquid at room temperature. Iodine trichloride melts at 101 °C. [1] Most interhalogens are covalent gases. Some interhalogens, especially those containing bromine, are liquids, and most iodine-containing interhalogens are solids.
