Popis:	The thermally reversible processes of melting and crystallization of the [1,2,5]oxadiazolo[3,4-e][1,2,3,4]tetrazine-4,6-dioxide–2,4-dinitro-2,4-diazapentane equimolar molecular complex produced in various technological modes of its isolation from the melt are studied and optimized by using turbidimetry, optical microscopy, and differential scanning calorimetry. The kinetic factors of the stepwise crystallization of the complex related to both the formation of nucleation sites and growth of the crystals are identified. A colorimetric method for controlling the phase purity and evaluating the content of impurities in the molecular complex after their preliminary identification by infrared spectroscopy is developed.
