Novel compounds are provided in the form of a salt having the structure of formula (I) or formula (II) wherein: R1 is selected from the group consisting of H, C1-C24 alkyl, C2-C24 alkenyl, C2-C24 alkynyl, C5-C20 aryl, C6-C24 alkaryl, and C6-C24 aralkyl; R2 is H, C1-C24 alkyl or nitro; X is O or NR3 in which R3 is H, C1-C24 alkyl or nitro; Zm+ is a monovalent cation, a divalent cation, or a trivalent cation; M+ is an alkali metal cation; and m and n are 1, 2 or 3, with the proviso that the compound contains at least one nitro group. Exemplary such compounds are the ammonium salt of the N-hydroxyl-N'-nitrourea (NHNU) monoanion and the disodium salt of the NHNU dianion. Also provided, as novel compositions of matter, are N-hydroxyl-N'-nitrourea and N-hydroxyl-N-nitroguanidine in electronically neutral form. The compounds are useful in a variety of contexts, but are primarily useful as high energy oxidizing agents in explosive compositions, propellant formulations, gas-generating compositions, and the like. Compositions containing the compounds are also provided, including energetic compositions, as are methods for synthesizing the compounds.
