Source of material
The title compound, C3H6N4O5, was prepared from hexamine by nitration. It was recrystallized from acetone solution at room temperature to give colorless crystals suitable for single-crystal X-ray diffraction.
Experimental details
H atoms were positioned geometrically with C—H = 0.97 , and constrained to ride on their parent atoms, with Uiso(H) = 1.2 times Ueq(C).
Discussion
3,5-dinitro-1,3,5-oxadiazinane is obtained as a by-product in the synthesis of RDX (1,3,5-trinitro-1,3,5-triazinane) from hexamine by nitration. As part of our search for nitrlysis mechanism of hexamine, the title compound was separated and its structure was characterized. As shown in the figure, the oxadriazine ring adopts a chair conformation two nitro groups stand on the same side of the triazine ring.
