On exposure to 60Co γ rays at 77 K a range of alkylmercury(II) halides give e.s.r. signals indicative of two types of radical: one, exhibiting only small hyperfine interaction with magnetic mercury isotopes, is identified as R2ĊHgX; and the other, with very large hyperfine coupling to mercury, as gR. Dimethylmercury gives the radical H2ĊHgMe together with a species thought to be (Me2Hg)[graphic omitted]. Structures of these radicals and mechanisms of the processes are discussed.
