Hydrogen Peroxide Solvates of 2,4,6,8,10,12‐Hexanitro‐2,4,6,8,10,12‐hexaazaisowurtzitane

Abstract

Two polymorphic hydrogen peroxide solvates of 2,4,6,8,10,12-hexanitro-2,4,6,8,10,12-hexaazaisowurtzitane (CL-20; wurtzitane is an alternative name to iceane) were obtained using hydrated α-CL-20 as a guide. These novel H O solvates have high crystallographic densities (1.96 and 2.03 g cm , respectively), high predicted detonation velocities/pressures (with one solvate performing better than ϵ-CL-20), and a sensitivity similar to that of ϵ-CL-20. The use of hydrated materials as a guide will be important in the development of other energetic materials with hydrogen peroxide. These solvates represent an area of energetic materials that has yet to be explored.

Comparison of 1‐Ethyl‐5H‐tetrazole and 1‐Azidoethyl‐5H‐tetrazole as Ligands in Energetic Transition Metal Complexes

“…No measurements regarding electrostatic discharge could be performed due to the physical state of both ligands. The highest stability towardi mpact of all ECC (15 J, sensitive) is possessed by the only zinc coordination compound 6,w hich has to be considered as very sensitive because of its friction sensitivity.C omparing the perchlorate complexes reveals, that all have to be considered as very sensitive (6,8)o re ven extremelys ensitive ( 5,7), except compound 9, which is stated as sensitive, also possessing the highest stability toward friction of all investigated perchlorates. The sensitivity toward impact of the ECC based on perchlorate and AET increasesi nt he followingo rder:Z n 2 + (15 J) < Fe 2 + (3 J) < Cu 2 + (< 1J)% Ag + (< 1J)a nd in the following order against friction: Zn 2 + (40 N) < Cu 2 + (15 N) < Fe 2 + (3.75 N) < Ag + (0.6 N) ( Figure 12).…”

“…Over 95 %o fa ll missile launches,s hooting, and explosions within the police forces or military are done exclusively for training purposes in "friendly" areas, [4] leading to an ongoing research for new and more ecofriendly energetic materials. [5][6][7][8][9][10] Since the discovery of phenyl azide in 1864, [11] azido organic compounds have attracted the attention of chemists due to their unique characteristics. The initial postulationo fC urtius and Hantzsch for the structurald etermination of organic azides suggested acyclic 1H-triazirine structure.…”

Hydrogen Peroxide Insular Dodecameric and Pentameric Clusters in Peroxosolvate Structures

“…[11] Thus as eries of theoretical studies on H 2 O 2 and H 2 O 2 -water clusters was recently performed. [12][13][14][15][16] Surprisingly,t he experimental X-ray data on such clusters are very sparse.Despite the particular attention attracted to structures of hydrogen-bonded complexes of H 2 O 2 , [17][18][19][20] only structures containing low-order D3 peroxide clusters [20] and C1 peroxide and peroxide-water chains have been reported to date [21,22] (D3 and C1 are Infantes-Motherwell notion [23] ). In contrast, hundreds of large water clusters are known, [23] especially in protein cavities.…”

Synthesis, Crystal Structure, and Thermal Behavior of a Novel Insensitive Energetic Cocrystal Composed of 3,3′‐Bis(1,2,4‐oxadiazole)‐5,5′‐dione and 4‐Amino‐1,2,4‐triazole

“…In previous studies, the formation of multicomponent materials (solvates, and salts, ) from two energetic molecules has become an effective and easy method to tune the physical characteristics of energetic materials. Recently, co‐crystallization has emerged as an alternative approach to synthetic modification.…”
