[Abstract]:2- (dinitromethylene) -1n 3-diazacyclopentane (DNDZ) is synthesized from FOX-7. It is an important derivative of FOX-7 nucleophilic reaction. It is a new type of energetic materials and has excellent high energy passivity. DNDZ was the main ligand and organic amine solution was used as auxiliary ligand to coordinate with metal (CD ~ (2 +) Zn). During the reaction with methylamine solution, DNDZ formed N- (2-aminoethyl) -2o _ 2-dinitroacetamide (ADNA). For the first time in the process of reaction with methylamine solution. In this paper, five complexes were synthesized, including two complexes of DNDZ and three complexes of ADNA, and the single crystals of four complexes were grown. At the same time, the crystal structure of these complexes was determined by X-ray diffractometer. The data are analyzed and processed to understand the molecular structure of these complexes, the intermolecular force and the stacking of crystals. CD (NH_3) 4 (DNDZ) 2: monoclinic S / S P _ (21 / c) space group; [CD (CH_3NH_2) _ 2 (ADNA) _ 2] n: triclinic system P _ (-1) space group; [CD (C_2H_5NH_2) _ 2 (ADNA) _ 2] n: triclinic crystal system P-1 space group; [CD (CH_3NH_2) _ 2 (ADNA) _ 2 (ADNA) _ 2]; [CD (C_2H_5NH_2) _ 2 (ADNA) _ 2] n: triclinic crystal system P _ (-1) space group; [CD (CH_3NH_2) 2 (ADNA) 2] n: P _ (-1) space group; The DSC and TG/DTG curves of the five complexes were measured under non-isothermal conditions, and their thermal decomposition behaviors were studied. The kinetic parameters of their thermal decomposition were calculated by Kissinger and Ozawa methods. The continuous specific heat capacity of CD (NH_3), [CD (CH_3NH_2) _ 2 (ADNA) _ 2] and Zn (NH_3) _ 2 (DNDZ) _ 2 was measured. On the basis of the specific heat capacity equation, the molar heat capacities of the complexes at 298.15 K were calculated to be: 642.0608.6636.6 and 521.3 J mor1 K-1, respectively. Their adiabatic time to explosion time is estimated, and the calculated results are respectively: 59.422.7 / 48.6 / 64.3s. The thermal stability of CD (NH_3), [CD (NH_3) _ 2 (ADNA) _ 2] n, [CD (CH_3NH_2) _ 2 (ADNA) _ 2] _ n, [CD (C_2H_5NH_2) _ 2 (ADNA) _ 2] _ S _ n and Zn (NH_3) _ 2 (DNDZ) _ 2 are measured to evaluate their thermal stability.
