NAME: dichlorine hexoxide, chloryl chlorate
FORMULA: Cl2O6
AUTHOR(YEAR): GoodeveRichardson(1937)
T: 273-276.5K
λ: 200-350nm
BIBLIOGRAPHY: C.F. Goodeve and F.D. Richardson, "The absorption spectrum of chlorine trioxide and chlorine hexoxide", Trans. Faraday Soc. 33, 453-457 (1937); DOI: 10.1039/TF9373300453
COMMENTS: Structure: O3ClOClO2

Graphical interpolation of the absorption curve shown in Fig. 1 by

R.D. Hudson, "Chlorofluoromethanes and the stratosphere", NASA Reference Publication 1010 (1977), pp. 33 and 36

The spectrum has originally been attributed to ClO3

Because of its shape and in spite of the low absorption cross sections, the spectrum has been attributed to Cl2O6 by

M.I. Lopez and J.E. Sicre, "Physicochemical properties of chlorine oxides. 1. Composition, ultraviolet spectrum, and kinetics of the thermolysis of gaseous dichlorine hexoxide, J. Phys. Chem. 94, 3860-3863 (1990); DOI: 10.1021/j100372a094
