“…As polydentate building blocks, 1,2,4-triazole and its derivatives combine the coordination geometries of both pyrazoles and imidazoles, exhibiting a strong ability to bridge metal ions to afford polynuclear structures [10]. More practically, substituted 1,2, 4-triazoles are excellent ligands of energetic complexes, such as 4-amino-1,2,4-triazole [11][12][13], 3,5-diamino-1,2,4-triazole [14], and 3-azido-1,2,4-triazole [15]. Recently, MOFs [16] as a new concept for coordination polymers have attracted interest since the structure and the stability can be improved.…”

Two coordination polymers, [Mn 2 (HATr) 4 (NO 3 ) 4 ·2H 2 O] n (1) and [Cd 2 (HATr) 4 (NO 3 ) 4 ·H 2 O] n (2), were obtained from the corresponding metal nitrate with 3-hydrazino-4-amino-1,2,4-triazole (HATr) and characterized through elemental analysis and IR spectroscopy. The structures were determined by single-crystal X-ray diffraction. The results show that both complexes crystallize in the triclinic P-1 space group and have six-coordinate distorted octahedral structures, which are made up of infinite 1-D chains running along the a axis of metals linked by bridging-chelating HATr ligands. The coordination sites are in agreement with the computational results. Additionally, the decomposition temperatures were determined by differential scanning calorimetry and the kinetic parameters were calculated using Kissinger's and Ozawa-Doyle's methods; the energies of combustion for 1 and 2 were −7186.25 and −6922.53 kJ M −1 and the enthalpies of formation were obtained as −1002.35 and −457.27 kJ M −1 , respectively.

“…These materials have exhibited promising applications as pyrotechnics and primary explosives − and have been constructed exclusively with strong coordination bonds between nitrogen-rich ligands and metal ions. Until now, their structures and properties primarily differ in the various metal ions and organic ligands with different backbones used. − However, the modulation of their energetic properties via the introduction of different energetic groups on the same backbone (ligand) has been rarely reported. The proposed modulation also facilitates exploring the effects of energetic groups on the structures and properties of energetic complexes, which are important for the better design of new high-performance energetic materials.…”

The modification of the properties of energetic materials is significant not only for gaining insight into the correlation between the structure and properties but also for various applications. In this study, three bis-1,2,4-triazole derivatives containing different energetic groups such as NH2, NO2, and NHNO2 (5,5′-diamino-3,3′-bis-1,2,4-triazole (H2DABT), 5,5′-dinitro-3,3′-bis-1,2,4-triazole (H2DNBT) and 5,5′-dinitroimino-3,3′-bis-1,2,4-triazole (H2DNABT)) were chosen as ligands to tune the structures and energetic properties of their complexes. Single-crystal X-ray diffraction studies show that as the modifying groups on the bis-1,2,4-triazole ligand were varied from NH2 to NO2 and NHNO2, the densities of the resultant complexes gradually increased from 1.838 g cm–3 to 1.978 g cm–3 and 2.049 g cm–3 for Cu-based complexes, while for Zn-based complexes, the densities also showed a gradual increase from 1.818 g cm–3 to 2.044 g cm–3 and 2.056 g cm–3. Additionally, the thermal stabilities and sensitivities of these complexes were also determined, and their detonation properties were calculated by the modified Kamlet method. As a result, the energetic performances of these resultant complexes were successfully modulated. This work may provide an effective approach to modulate the energetic properties of complexes via introduction of different energetic groups into the ligands.

“…These materials mostly combine facile syntheses, good thermal stabilities as well as energetic properties comparable to that of the prominent primary explosive lead azide, which suffered from its high toxicity. Nitrogen‐rich heterocycles and chain ligands of hydrazine derivative with several lone‐pair electrons,such as 5‐nitrotetrazole,12–14 1,5‐diaminotetrazole,15–17 3‐azido‐1,2,4‐triazole,18–20 carbohydrazide (CHZ)21,22 and hydrazine,23 are typically used for the synthesis of energetic complexes.…”

Abstract. Through a one-pot reaction of NiCO 3 ·2Ni(OH) 2 ·H 2 O, aminourea hydrochloride (SCZ·HCl) and 2,4,6-trinitroresorcinol (TNR), a halogen-free and lead-free chelating energetic material (CEM) [Ni(SCZ) 3 ]TNR was synthesized. We confirmed the structure of [Ni(SCZ) 3 ]TNR by infrared spectroscopy, X-ray diffraction, and elemental analysis. The complex is triclinic with P1(2)/n space group. Cell parameters are: a = 1.04008(17) nm, b = 1.3719(2) nm, c = 1.4897(2) nm, V = 2.0337(6) nm 3 , Z = 4. The central nickel atom is six-coordinate with three oxygen atoms of carbonyl groups and three terminal nitrogen atoms of the hydrazine groups from three SCZs to form a distorted octahedron.
