In the title salt, CH7N2+·C6H2N3O7−, the dihedral angles between the three nitro groups and the plane of the benzene ring are 22.4 (2), 35.3 (2) and 2.8 (2)°. In the crystal, the components are linked by N—H⋯O and N—H⋯N hydrogen bonds into a two-dimensional network parallel to (10).

1-methylhydrazine (0.02 mol) was added to a solution of picric acid (0.02 mol) in 30 ml ethanol at room temperature, the mixture was stirred for 0.6 h to afford the title compound. Single crystals suitable for X-ray structural analysis was obtained by slowly evaporating from distilled water at room temperature.
H atoms were fixed geometrically and allowed to ride on their attached atoms, with C—H distances = 0.93–0.96 Å; N—H = 0.85-0.90 Å and with Uiso(H) = 1.2Ueq(C,N) or 1.5Ueq(Cmethyl).
The molecular structure of the title compound is shown in Fig. 1. The dihedral angles between the three nitro groups and the plane of the benzene ring are 22.4 (2), 35.3 (2) and 2.8 (2)° for the groups containing N1, N2 and N3. In the crystal, the components are linked by N—H···O hydrogen bonds into a two-dimensional network paralell to (101).

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

The molecular structure of the title compound is shown in Fig. 1. The dihedral angles between the three nitro groups and the plane of the benzene ring are 22.4 (2), 35.3 (2) and 2.8 (2)° for the groups containing N1, N2 and N3. In the crystal, the components are linked by N—H···O hydrogen bonds into a two-dimensional network paralell to (101).
