• 3-Diethylamino-6-phenyl-1,4,2,5-dithiadiazine, on standing in air at room temperature, decomposed to afford 5-diethylamino-3-phenyl- and 3,5-bis(diethylamino)-1,2,4-thiadiazoles, whereas in the melt and in solution it was remarkably stable. With increasing bulkiness of substituents (Ar and/or NR<SUB>2</SUB>) in 1,4,2,5-dithiadiazines, their stability in the solid state clearly enhanced. Some interstack interactions in the crystal seem to favor the decomposition.
