“…The triaminoguanidinium cations follow structures published numerously in the literature such as, for example, triaminoguanidinium nitrate. [33] The densities of 1.550 g cm À3 (7) and 1.583 g cm À3 (9) are higher than those of 2 and 4-6. Single crystals could be obtained after the reaction of 1and 2-oxido-5-cyanotetrazolate with copper sulfate.…”

In this work we report on the syntheses of energetic salts of cyanotetrazolate-1- and -2-oxides; this offers a unique ability to compare the effects of tetrazole 1- versus 2-oxidation. 5-Cyanotetrazolate-2-oxide can be synthesized by oxidation of the 5-cyanotetrazolate anion with Oxone, while the corresponding 1-oxide was synthesized by the rearrangement of azidoaminofurazan. Both chemical (multinuclear NMR, IR, and Raman spectroscopies, mass spectrometry, etc.) as well as explosive (impact, friction, and static sensitivities) properties are reported for these energetic salts. Calculated explosive performances using the EXPLO5 computer code are also reported. We furthermore detail the chemistry of these two anions, and their ability to form tetrazole-carboxamides, dihydrotetrazines, and tetrazines. The ability to hydrolyze cyanotetrazole oxides to their amides was demonstrated by two copper complexes. Several crystal structures of these species are presented in addition to full chemical characterization. Finally, the unique 1,4,-bis(2-N-oxidotetrazolate)-1,2,4,5-tetrazine anion was characterized as an energetic material as its ammonium salt.

“…The burning rates were measured in a constant-pressure window bomb of 1.5 L volume in nitrogen in the pressure range 0.1-10 MPa. Samples to test were prepared in the form of pressed cylinders of 0.92-0.94 theoretical maximum density (1.594 g cm À3 [15]) confined in transparent acrylic tubes of 7 mm inner diameter. Prior to pressing, the material was thoroughly comminuted in order to produce samples with a minimum possible pore size, thus minimizing the possibility of flame propagation between particles.…”

The combustion behavior of triaminoguanidine nitrate (TAGN) was investigated over a wide pressure range and a detailed combustion mechanism has been proposed. Temperature profiles in the TAGN combustion wave were measured with thin tungsten‐rhenium microthermocouples. It was shown that the surface temperature in combustion of TAGN as well as for other onium salts is controlled by the process of dissociation. The burning rate of TAGN is governed by processes in the condensed phase.

“…The bonding distances reveal some interesting features. The formal double bond, C(1)-N(2), is 0.05 .A longer than the two other C-N bonds of the guanidine moiety, which are of approximately the same length as the C-N bonds in protonated guanidine moieties (Cotton, Day, Hazen & Larsen, 1973;Cotton, Day, Hazen, Larsen & Wang, 1974;Larsen, 1975;Berthou, Laurent & Nakajima, 1976;Bracuti, 1979), and only slightly longer than in the guanidinium ion (Adams & Ramdas, 1978). The nitrimino group closely resembles that in trimethylammonionitramidate (Cameron, Hair & Morris, 1972), where the zwitterionic structure is evident, and that in cyanonitramide, obtained from counting statistics modified for experimental instability.…”
