Structural Diversity and Properties of M(II) Coordination Compounds Constructed by 3-Hydrazino-4-amino-1,2,4-triazole Dihydrochloride as Starting Material

Abstract

Twelve metal coordination compounds with two triazole derivatives, namely, {[Mn(HATr)2](ClO4)2}n (1), [Mn(HATr)3]Cl(ClO4) (2), [Co3(ATr)6(H2O)6](ClO4)6·4.5H2O (3), [Co(HATr)3]Cl(ClO4) (4), [Co2Cl2(HATr)2(H2O)2(CH3OH)2]Cl2·2H2O (5), [Ni3(ATr)6(H2O)6](ClO4)6·4.5H2O (6), [Ni(HATr)3]Cl(ClO4) (7), [Ni2Cl2(HATr)2(H2O)4](ClO4)2·4H2O (8), [Ni2(HATr)2(H2O)6](ClO4)4·2H2O (9), {[Zn(HATr)2](ClO4)2}n (10), [Zn(HATr)3]Cl(ClO4) (11), and {[Cd4(HATr)8](CdCl4)Cl2(ClO4)4}n (12), when HATr = 3-hydrazino-4-amino-1,2,4-triazole and ATr = 4-amino-1,2,4-triazole, were prepared under diverse conditions and structurally characterized. Compounds 1, 10 and 12 exhibit one-dimensional zigzag chain structures; 2, 4, 7, and 11 possess mononuclear structures; 3 and 6 display trinuclear structures, while 5, 8, and 9 feature binuclear structures. Hydrogen bonds link these compounds into three-dimensional structures. The thermal stability and energetic properties also were determined.

Study of Six Green Insensitive High Energetic Coordination Polymers Based on Alkali/Alkali‐Earth Metals and 4,5‐Bis(tetrazol‐5‐yl)‐2 H‐1,2,3‐triazole

“…[37,38] However,i deal insensitive high-energetic coordination polymers (IH-ECPs) conforming to the concept of IHEs with outstanding insensitivity (IS > 40 J, FS > 360 N) and detonation velocity( D > 9kms À1 )a re rare in the published literature. [39][40][41][42][43][44][45][46][47] To date, only two high-performance IH-ECPsh ave been constructed based on tetrazole derivatives:4 ,4'oxybis(3,3'-(1 H-5-tetrazol))furazan [46] and bis(tetrazole)methane. [47] As the primary energy source, these nitrogen-rich compounds not only have abundant inherent energetic bonds between atoms of C/N and N/N, but also will bring diversec oordination structures through high nitrogen aromatic moieties.…”

“…Inspired by this, many ECPs have been synthesized and characterized during last decade since the first one was achieved by Hope‐Weeks and co‐workers . However, ideal insensitive high‐energetic coordination polymers (IH‐ECPs) conforming to the concept of IHEs with outstanding insensitivity (IS>40 J, FS>360 N) and detonation velocity ( D >9 km s −1 ) are rare in the published literature . To date, only two high‐performance IH‐ECPs have been constructed based on tetrazole derivatives: 4,4′‐oxybis(3,3′‐(1 H ‐5‐tetrazol))furazan and bis(tetrazole)methane .…”

Coordination polymerization of nitrogen-rich linkers and dicyanamide anions toward energetic coordination polymers with low sensitivities

“…Recently, energetic coordination polymers (ECPs) constructed from high-energy ligands and metal centres have become promising candidates for high energy materials with enhanced stabilities because of their reinforced architectures, good mechanical strength, high energetic output, and reliable thermostability. 15–19 Many scientists have reported new ECPs for a variety of applications in EMs by the strategy of tuneable compositions and structures of the ECPs. To date, the applications of ECPs can be mainly summarized as being related to two directions: (i) insensitive secondary explosives and (ii) primary explosives with high mechanical sensitivities.…”

Lithium-Promoted Formation of M-2AZTO-Li (M = N2H5+ or NH3OH+ and AZTO = Anion of 1-Hydroxytetrazole-5-hydrazide)-Type “Quaternary” Complexes with Nitrogen-Rich Characteristics: Construction of Novel Insensitive Energetic Materials

“…Energetic complexes are typically produced in the following three forms (Figure A–C): (A) high-energy anion-metal-cation, − (B) high-energy cation-metal-ion-oxygen-rich-anion, − and (C) azole anion-heavy metal-cation-azide anion. − The foregoing three types of complexes exhibit different characteristics in terms of their physicochemical properties, and of these, types A and B tend to form high-energy complexes with a high oxygen content; a majority of such complexes also have a high mechanical sensitivity, facilitating their use as primary explosives, oxidizer combustion promoters, or heat-resistant explosives. Furthermore, C-type complexes are more likely to form nitrogen-rich structures and exhibit favorable thermal stabilities.…”
