Figure 1 Displacement ellipsoid plot (Barbour, 2001) of C6H16N4O4.4H2O at the 50% probability level. H atoms are drawn as spheres of arbitrary radius. Unlabelled atoms in the tetrazinane derivative are related to labelled atoms by the symmetry operation (1-x, −y, 2-z). Two symmetry related water molecules are not shown. |
