An Easy Method to Prepare D₃ and C₂‐TATP Crystals

Abstract

D3 and C2 TATP structures interconvert at room temperature. Herein, an easy method to isolate both conformers is shown that consists of multiple recrystallization steps using different solvent and heating to boiling. Spectroscopic and physical measurements, such as Raman spectroscopy, X‐ray diffraction, and melting point analysis, showed that clear and opaque crystals, respectively, represent different conformations of TATP. Additionally, the transition energy between both conformers was estimated using the Raman shifts.

“…TATP was synthesized under strict safety controls to include restricted yield of less than 1 mg, low temperature conditions, and storing in acetonitrile solvent to mitigate risk. 21 Instrumental Setup. Explosive solutions were transferred to a piece of cotton in the bottom of a clean cuvette and exposed to a stream of air to ensure evaporation of all solvent.…”
