Two Isostructural Explosive Cocrystals with Significantly Different Thermodynamic Stabilities

Abstract

Irreconcilable differences: Electron-rich diacetone diperoxide is paired with the electron-deficient rings of trichloro- and tribromotrinitrobenzene to form energetic cocrystals by design. Though the two cocrystals are isostructural, the former is very stable while the later exhibits a rare metastability and favors separation.
