Are DTTO and iso -DTTO Worthwhile Targets for Synthesis?
Autor: Karl O. Christe, David A. Dixon, Monica Vasiliu, Ross I. Wagner, Ralf Haiges, Jerry A. Boatz, the late Herman L. Ammon
Publikováno v: Propellants, Explosives, Pyrotechnics. 40:463-468
Theoretical calculations were carried out for the isomeric di-1,2,3,4-tetrazine tetraoxides (DTTO and iso-DTTO). The most important explosion performance parameters, the detonation pressure and detonation velocity, are dominated by the densities and

Ten new salts that pair triazolium and imidazolium cations with closo-icosahedral anions [B(12)H(12)](2-) and [CB(11)H(12)](-) were synthesized in water solvent using an open-air, benchtop method. These unreported [Heterocyclium](2)[B(12)H(12)] and [

A collaborative workshop was held in May 1999 at the Cambridge Crystallographic Data Centre to test how well currently available methods of crystal structure prediction perform when given only the atomic connectivity for an organic compound. A blind
