Source of material
Dissolve 0.5 g 4,6-dinitrosamino-1,3,5-triazine-2-one (DNAM) into 200 ml of water, react with 0.2 g Mg(OH)2 for half an hour, and use distillation under reduced pressure to remove 2/3 of the water. Finally evaporated at room temperature to obtain crystals suitable for X-ray diffraction.
Experimental details
Hydrogen atoms were placed in plausible positions and constrained to ride on their parent atoms.
Comment
Triazine have the advantages of high density, high positive enthalpy of generation and good thermal stability. They can be used as gas generating agents, solid propellant fuels, and pyrotechnic agents [5, 6]. DNAM, prepared by one-step nitrification of melamine, is a triazine-containing material with good performance parameters [7], [8], [9], [10].
As shown in the figure, the crystal structure of the title compound is formed by DNAM after removing two hydrogen atoms as anions and hexaaqua magnesium complexes as cations. All bond length and bond angles are in the normal range [11]. Compared with the DNAM crystal structure, the bond length and angle are slightly changed. The dihedral angle between the nitro group N7-O5-O4 and the azine ring is increased from 10.05° to 24.80°, and the dihedral angle between the nitro group N1-O2-O3 and the azine ring is reduced from 10.05° to 5.14°.
