“…We consider that, like at the combustion of glycine-nitrate compositions [7,16], the formation of metallic nickel in air can be associated with the presence of nitrogen in imidazole. As a rule, one of the thermolysis products of N-containing organics is ammonia [16,[53][54][55], which can participate in nickel oxide reduction by reaction (2) even in air.…”

To study their composition, the ATR FTIR spectra were analyzed (Figure 8).…”

In this work two approaches to the synthesis of energetic complex compound Ni(Im)6(NO3)2 from imidazole and nicklel (II) nitrate were applied: a traditional synthesis from solution and a solvent-free melting-assisted method. According to infrared spectroscopy, X-ray diffraction, elemental and thermal analysis data, it was shown that the solvent-free melt synthesis is a faster, simpler and environmentally friendly method of Ni(Im)6(NO3)2 preparation. The results show that this compound is a promising precursor for the production of nanocrystalline Ni-NiO materials by air-assisted combustion method. The combustion of this complex together with inorganic supports makes it possible to synthesize supported nickel catalysts for different catalytic processes.

“…2,2 0 -Bipyridine has been a useful molecule and is being widely used by various research groups involving it as a ligand for complex formation [21][22][23][24][25]. Recently, much attention has been given to energetic transition metal perchlorate complexes having heterocyclic ligands such as imidazole [26], 4,4 0 -bipyridine [27], hexamethylenetetramine [28,29], 3(5)-hydrazino-4-amino-1,2,4-triazole (HATr) [30], 4-amino-1,2,4-triazole [31], 2,2 0 -bipyridine [1][2][3], 2-aminopyridine [32] and 4-aminopyridine [33].…”

The mixed-ligand mononuclear hexacoordinate cadmium perchlorate complex [Cd(2,2 0 -bipy) 2 (H 2 O) (ClO 4 )]ClO 4 was synthesized and characterized by FT-IR, elemental analysis and X-ray crystal structure determination. Thermal characteristics of the complex were studied by thermogravimetry (TG), differential thermal analysis and differential scanning calorimetry. The complex is stable at normal temperature and undergoes dehydration in between the temperature range 95-200°C with loss of coordinated water (2.8 %). Thereafter, on increasing temperature, dehydrated complex shows some gradual mass loss followed by fast decomposition at higher temperature (265-380°C). The kinetic parameters for the decomposition of the complex were investigated by applying modelfitting and isoconversional method on isothermal TG data recorded at five different temperatures. To explore the response of complex to sudden high heat, explosion delay time was recorded at five different temperatures, and kinetics of explosion was investigated using these data.

“…Such type of complexes has been proved to be a strong burning rate modifier for hydroxyl terminated polybutadiene-ammonium perchlorate (HTPB-AP) based propellants [4,5]. In search of insensitive high energetic materials, a strong interest is being given by the researches on such type of complexes (having oxidizing and reducing group in one molecule) and they have been synthesized and their properties have been extensively investigated [5][6][7][8][9][10][11][12][13][14]. In the present paper, we report the preparation, characterisation, thermolysis, and explosion characterisation of nickel perchlorate complex with n-propyl amine, water, and ClO 4 − as ligands.…”

Complex of nickel perchlorate with n-propylamine has been synthesised with molecular formula [Ni(n-pa) 3 (ClO 4 )(H 2 O)]ClO 4 . It has been characterised by elemental analysis, thermogravimetry, UV-VIS, and IR spectroscopic data. Thermal properties have been investigated by thermogravimetry (TG) in static air and by simultaneous thermogravimetry-derivative thermogravimetrydifferential thermal analysis (TG-DTG-DTA) in flowing nitrogen atmosphere. Kinetics of thermolysis has been analysed applying model-fitting and model-free isoconversional method on isothermal TG data recorded at five different temperatures. To observe the response of complex towards fast heating, explosion delay time has been recorded at various temperatures and kinetics of explosion has been studied using these data.
