High Energy Materials is a term that is used for explosives, propellants and pyrotechnics. Explosives are used for military applications. 5-Picrylamino-1,2,3,4-tetrazole(PAT) is an explosive substance. In this study the reactions of the 5-Picrylamino-1,2,3,4-tetrazole(PAT) with nanostructures of fullerene and boron nitride nano-cages in different conditions of temperature, with density function...

 In this article, synthesis of the explosive synthesis of 5- picrylamino-1, 2, 3, 4-tetrazole (PAT) from the reaction of 5-amino-1, 2, 3, 4-tetrazole with picryl chloride in different conditions of temperature, with density functional theory method were studied. For this purpose, at first the material contained in the both sides of reaction were geometrically optimized, then th...

The metal-organic framework [Cd15(5MT)18(OH)4(SO4)4] (5-MT = 5-methyl-1H-tetrazole) with an unprecedented Cd(3)(micro3-OH)(micro3-SO4) core and two kinds of tetrazole coordination modes was formed by self-assembly and in situ synthesis of the 5-MT tetrazole ligand; the structure exhibits an unusual 3(9) x 4(12) x 5(15) topological network and shows reversible shrinkage and expansion in a crysta...

A study of the effect of the tetrazole moiety, a cis-amide bond surrogate, on the Cu(II) coordinating properties of oligopeptides is reported. Insertion of the tetrazole moiety Psi[CN(4)] into the peptide sequence of [D-Ala(2)]deltorphin I changes considerably the coordination ability of the peptide. Potentiometric and spectroscopic results show that if the tetrazole moiety is in a suitable pos...

High-level ab initio electronic structure calculations, including extrapolations to the complete basis set (CBS) limit, were performed, and highly precise relative energies of five-member N-heterocycles were determined. Nitrogen-containing heterocycles studied included tautomers of tetrazole (CH(2)N(4)) and triazoles (C(2)H(3)N(3)). Valence focal-point analysis of 1H-tetrazole, 2H-tetrazole, 5H...
