A new compound, 1,1-diamino-2,2-dinitroethylene suitable for use as an explosive, as well as an intermediate for preparing the compound consisting of a heterocyclic 5- or 6-ring of the general formula
wherein n=at least 1. The compound is prepared by nitrating a heterocyclic 5- or 6-ring containing the structural element
wherein Y is an alkoxy group, with a nitrating acid at a low temperature, preferably 0-30° C., and selecting the acidity of the nitrating acid for obtaining a substantial yield of a product containing the structural element
and hydrolyzing said product in an aqueous medium for separating 1,1-diamino-2,2--dinitroethylene which is recovered as a precipitate.
