The γ-irradiation of dipotassium difluoromalonate monohydrate led to the formation of two molecular configurations of the ĊF 2 CO 2 − radical in addition to the previously identified ĊF(CO 2 − ) 2 radical. A comparison of the α-fluorine coupling in the two forms of the ĊF 2 CO 2 − radical indicates that loss of a carboxylate group nearly coplanar with the C—C—C plane in the undamaged molecule is favored.
