✦ Synopsis

H , =C, ' * N and 19%g N M R data were obtained for organomercury fuIminates, RHgCNO (R=Me, Ph, CNO). The relatively slow relaxation processes effective for the quadrupolar nitrogen muclei of these compounds allow the detection of -g-l4N scalar coupling constants. This feature is ascribed to the presence of low electric field gradients around the I4N nucleus, owing to the presence of the mercury atom. In mercury fulminate, the 19%g nucleus appears to be coupled with two equivalent '3 nuclei, thus indicating the existence of a covalent structure Hg(CNO), in solution.
