1 Source of material
An appropriate amount of 2-amino-4,5-dicyan-imidazole, hydrochloric acid and potassium permanganate were added to the reactor. The temperature of the reactor was reduced to 273 K and the reactions are for 2 h. After the end of the reaction, the solids are removed and the filtrate is retained. The solvent in the filtrate is removed by a rotary evaporator to obtain white solid. The white solid was separated by column chromatography using petroleum ether and ethyl acetate as eluent. The solution obtained by column chromatography was evaporated at room temperature to obtain the colorless block shaped crystals.
2 Experimental details
Hydrogen atoms were placed in their geometrically idealized positions and constrained to ride on their parent atoms.
3 Comment
Azole heterocyclic compounds are a class of high-energy nitrogen-rich energetic materials. 5 , 6 Imidazole compounds are currently the focus of research on field of energetic materials due to good thermal stability and a large number of modification sites. 7 , 8 , 9
The title compound is cocrystal of two 2,2′-(hydrazine-1,1-diyl)bis(1H-imidazole-4,5-dicarbonitrile) molecules and three methanol molecules. The bond lengths and angles are in the expected ranges. 2,2′-(hydrazine-1,1-diyl)bis (1h-imidazole-4,5-dicarbonitrile) molecules are formed by connecting two imidazole planes by –N–NH2 structure. The two imidazole planes form a small angle and the dihedral angle is only 1.637°. Four hydrogen bonds are formed within 2,2′-(hydrazine-1,1-diyl)bis(1H-imidazole-4,5-dicarbonitrile) molecules. The bond lengths of hydrogen bonds are 2.696, 2.745, 2.441 and 2.207 respectively. The four carbon atoms of C2, C3, C7 and C8 are connected with four –CN groups and each –C–CN triatom structure is collinear. The above collinear structure is the same as the structure of 2-amino-4,5-dicyan-imidazole. 10
2,2′-(Hydrazine-1,1-diyl)bis(1h-imidazole-4,5-dicarbonitrile) is synthesized from two 2-amino-4,5-dicarbonitrile molecules. During the reaction, the amino group of one 2-amino-4,5-dicarbonitrile molecule is removed, and two hydrogen atoms of another 2-amino-4, 5-dicyanimidazole is removed. The two intermediates are connected by nitrogen atom and the free amino groups is attached to nitrogen atom, forming 2,2′-(hydrazine-1,1-diyl)bis(1h-imidazole-4,5-dicarbonitrile) molecule.
