Abstract
The title compound, C16H16N4O7, is close to being planar, with a dihedral angle of 3.15 (11)° between the benzene rings. The meth-oxy groups at the ortho- and para-positions of the 2,4,5-tri-meth-oxy-phenyl group are almost coplanar with the ring [deviations of the C atoms = 0.017 (2) and -0.025 (2) Å, respectively], whereas the meta-meth-oxy group deviates slightly [C-atom displacement = 0.162 (2) Å]. Both the ortho- and para-nitro groups are close to being coplanar with their attached ring [dihedral angles = 7.81 (12) and 8.56 (11)°, respectively]. An intra-molecular N-H⋯O hydrogen bond generates an S(6) ring motif. In the crystal, inversion dimers linked by pairs of N-H⋯O hydrogen bonds involving the same H atom as the intra-molecular bond generate R 2 (2)(12) loops. The dimers are linked by weak C-H⋯O inter-actions into sheets parallel to the (10-4) plane and the sheets are stacked by π-π inter-actions, with a centroid-centroid distance of 3.5974 (14) Å.Entities:

| Experimental. The crystal was placed in the cold stream of an Oxford Cryosystems Cobra open-flow nitrogen cryostat (Cosier & Glazer, 1986) operating at 100.0 (1) K. |
| Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds 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 > 2sigma(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. |
