Slight pyramidalization at the four N atoms leads to a twist boat conformation for the tetrazinane ring of the title compound, C4H8N4O2. In the crystal structure, the tetrazinane-3,6-dione molecules are disordered over two conformations with opposite ring puckerings, and are linked into two-dimensional sheets by N—H…O hydrogen bonding.
