(a) and (b) Projections of the structure of the title compound on to the planes of the two crystallographically independent nitrate anions, showing the N—H⋯O and C—H⋯O contacts. Atoms are identified as for Fig. 2. [Symmetry codes: (i) −1/2+x, 3/2−y, −1/2+z; (ii) −1+x, 1+y, z; (iii) 1+x, −1+y, z; (iv) 3/2−x, −1/2+y, 3/2−z.] |
