“…When the chloride ion concentration increases in the photo assisted Fenton reactions at pH 3 in situ formation of the FeCl 2+ complex takes place and this complex competes with the Fe (OH) 2+ complex for UV light photons and hence the rate of production of hydroxyl radical decreases. Cl − acts as a strong free radical scavenger and it reacts with OH • under acidic pH conditions [28][29][30]. …”

“…To our knowledge, only a few nitro-aromatic anion-based energetic salts have been reported: energetic salts of nitrophenol, [17a] picric acid, [17b] and trinitrophloroglucinol. [18] Conventionally, the energy of traditional nitro compounds such as TNT and 1,3,5,7-tetranitro-1,3,5,7tetraazacyclooctane (HMX) results primarily from the combustion of the carbon backbone, which consumes oxygen provided by the nitro groups.

“…Nitroaromatic compounds have also played an important role in the area of energetic materials (e.g., TNT, picric acid, 2,4,6‐trinitroanisole, and 1,3,5‐triamino‐2,4,6‐trinitrobenzene (TATB)).

Energetic salts based on dipicrylamine and its amino derivative were synthesized. All salts were fully characterized by multinuclear NMR spectroscopy ((1)H, (13)C), vibrational spectroscopy (IR), and elemental analysis. Ethylenediammonium di-DPA (DPA=dipicrylamine) and 1,3-diaminoguanidinium DPA were further confirmed by single-crystal X-ray diffraction. These salts exhibit reasonable physical properties, such as high densities (1.71-1.81 g cm(-3)), good thermal stabilities (T(d) =155-285 °C), and low solubilities in water. The impact sensitivity of 1-methyl-3,4,5-triamino-1,2,4-triazolium DPA is lower than that of 2,4,6-trinitrotoluene (TNT), and for some other energetic salts their impact sensitivities are comparable to that of TNT. Based on experimental densities and theoretical calculations carried out by using the Gaussian 03 suite of programs, all the salts have calculated detonation pressures (22.5-27.8 GPa) and velocities (7226-7917 m s(-1)) that exceed those of conventional TNT. The toxicities of these salts measured by luminescent bacteria toxicity tests are much lower than that of TNT, and two binary eutectic mixtures with melting points that fall between 70 and 100 °C were identified.

“…The decomposition of ATZ and [Cd(ATZ) 4 They are found to be thermally unstable comparing to the other two aminotetrazole complexes. In four ATZ derivatives, the decomposition temperature of (ATZ)TNPG is the lowest and the solid non-volatile residue mass at 600°C is also least, because TNPG -(trinitrophloroglucinol anion) is organic anion with -NO 2 groups, and the thermal decomposition mechanism of the salts can be expected to proceed through elimination of NO 2 , followed by a breakdown of the substituted benzene ring [29]. The high stability of the two ATZ coordination compounds is due to the coordination bond between the metal ions and ligands compare to salt compounds.…”

A novel 5-aminotetrazole mixed ligands complex of formula [Cu(PTS) 2 (ATZ) 2 (H 2 O) 2 ] (C 16 H 24 CuN 10 O 8 S 2 , PTS = p-toluenesulfonate, ATZ = 5-aminotetrazole) has been obtained by the reaction of 5-aminotetrazole with copper acetate and p-toluenesulfonic acid on heating in water. It was characterized by elemental analysis, FT-IR spectroscopy, and X-ray single crystal diffraction. The compound crystallizes in monoclinic system, space group P2 1 /c, Z = 2, a = 14.079(4) Å , b = 6.088(3) Å , c = 14.632(4) Å , b = 105.268(4)°, V = 1209.8(5) Å 3 . The central copper(II) cation is coordinated by two N atoms and four O atoms from two ATZ ligands, two water molecules and two p-toluenesulfonate ions to form a six-coordinated and distorted octahedral structure. Neutral ATZ is coordinated in the monodentate mode by the N(4) atom. The sulfonate group of the PTS ligand remains weak-coordinated modes and forms a number of hydrogen bonds with water molecule ligands and ATZ ligands. A supramolecular framework is connected by electrostatic interaction, weak coordinated bonding, hydrogen-bonding, and p-p interaction. The thermal decomposition mechanism of the title compound was predicted based on DSC, TG-DTG, and FT-IR analyses. Thermolysis of ATZ and its several derivatives is compared.
