Synergetic Explosive Performance through Cocrystallization

Abstract

A 1:2 cocrystal of 4H,8H-difurazano[3,4-b:3′,4′-e]pyrazine and hydroxylamine has been prepared that displays 1,3,5-triamino-2,4,6-trinitrobenzene-like sensitivity and performance. Most notably, the detonation properties of the cocrystal are better than that of the hypothetical 1:2 physical mixture and also higher than the theoretically predicted salt, making this a rare example of a cocrystal in which the detonation properties are synergistic. This was achieved through maximizing the intermolecular interactions through several hydrogen bonding and π-stacking.
