“…Most of the crystal water containing complexes can be dehydrated after heating (4,6,11,13,(14)(15)(16)19), indicated by an endothermic peak in the DSC curve, which is well-separated from the exothermic decomposition event. Some of the complexes decompose immediately after they start to lose their crystal water (3,5,9,14), whereas for 8, no endothermic event before decomposition can be observed, although it crystallizes as a dihydrate.…”

3-Amino-1-nitroguanidine (ANQ, 2) was synthesized via hydrazinolysis of nitroguanidine. By dissolving 2 in solutions containing transition metal salts, several complexes M(2+)(ANQ)2X2(H2O)y with M(2+) = Co, Ni, Cu, Zn as well as M(ANQ)2X(H2O)y with M = Ag could be isolated. In these cases, nitrate as well as perchlorate and chloride served as the respective anions X. Additionally, the ANQ complexes of Co, Ni, and Ag with dinitramide as the anion were synthesized from ANQ and silver dinitramide and by reacting the cobalt and nickel ANQ perchlorate complexes with ammonium dinitramide. The crystal structures of all described complexes were determined by low temperature single-crystal X-ray diffraction. Additionally, they were characterized using IR spectroscopy and elemental analysis. The decomposition temperatures were determined by differential scanning calorimetry and the sensitivities toward impact and friction were assessed using a BAM drophammer and a BAM friction tester (BAM = Bundesanstalt für Materialforschung und -prüfung). Additionally, the sensitivity toward electrostatic discharge was determined on a small-scale ESD device. The potential use of the nitrate, dinitramide and perchlorate containing species as primary explosives was investigated in a laser ignition test.

“…In addition, the halides as well as the sulfate salt also can be prepared by dissolving ANQ in dilute aqueous solutions of the respective mineral acids HCl, HBr, HI and H 2 SO 4 . However, it cannot react with HF, since the acidic strength of HF in aqueous solution is the weakest among all the hydrogenides, and HF is not able to protonate ANQ in aqueous solution [48]. Especially, the detonation pressure (42.7 GPa) and detonation velocity (9.551 km s −1 ) of ANGN are both superior to those of RDX, which can be considered as a potential candidate for high-energy-density compounds [18].…”

1-Amino-2-nitroguanidine (ANQ) is a high-energy nitrogen-rich compound with good detonation properties and low sensitivities. ANQ has only a central carbon atom with three small groups around it, including an amino, a hydrazine and a nitroxyl group. Though the molecular structure of ANQ is very simple, its reactivity is surprisingly abundant. ANQ can undergo various reactions, including reduction reaction, acylation reaction, salification reaction, coordination reaction, aldimine condensation reaction, cyclization reaction and azide reaction. Many new energetic compounds were purposely obtained through these reactions. These reactions were systematically summarized in this review, and detonation properties of some energetic compounds were compared. In the field of energetic materials, ANQ and some derivatives exhibit good application prospects.

“…11 However, little research was reported on 1-amino-2-nitroguanidine (ANG) which possesses better energetic properties (such as density, detonation velocity, detonation pressure and so on) than guanidine and its derivatives. 12,13 Herein, a nitrogen-rich energetic salt 1-amino-2nitroguanidinium nitrate (ANGN Scheme 1) was synthesized and fully characterized. Its crystal structure, thermal behavior and detonation properties were also investigated to give a better understanding of its physical and chemical properties.…”
