ABSTRACT: In the title compound, C(15)H(14)N(4)O(6), the dihedral angle between the aromatic rings is 3.7?(4)°. The nitro groups make dihedral angles of 6.0?(4) and 5.2?(4)° with the parent ring and are oriented at 6.0?(6)° with respect to each other. The meth-oxy groups are inclined at 54.0?(2) and 2.5?(3)° with respect to the benzene ring to which they are attached. In the crystal, mol-ecules are linked by weak C-H?O inter-actions. The mol-ecular conformation is consolidated by an intra-molecular N-H?O hydrogen bond.

Project description:In the title compound, C(13)H(9)ClN(4)O(4), there are two crystallographically independent mol-ecules in the asymmetric unit, which have very similar conformations. The C=N-N angles in each independent mol-ecule are 115.0 (2) and 116.6 (2)°, which are significantly smaller than the ideal value of 120° expected for sp(2)-hybridized N atoms. This is probably a consequence of repulsion between the nitro-gen lone pairs and the adjacent N-N bonds. Two bifurcated intra-molecular N-H⋯O hydrogen bonds help to establish the mol-ecular conformation and consolidate the crystal packing.

Project description:There are two crystallographically independent mol-ecules in the asymmetric unit of the title compound, C(15)H(14)N(4)O(5), with different conformations for the meth-oxy groups. The mol-ecules are both slightly twisted, the dihedral angles between two benzene rings being 8.37 (18)° in one and 7.31 (18)° in the other. In both mol-ecules, the two nitro groups are essentially coplanar with their bound benzene ring, with the r.m.s. deviation of the dinitro-benzene plane being 0.0310 (3) Å in one mol-ecule and 0.0650 (3) Å in the other. In each mol-ecule, an intra-molecular N-H⋯O hydrogen bond generates an S(6) ring motif. In the crystal, mol-ecules are linked by weak C-H⋯O inter-actions and stacked along the a axis through π-π inter-actions, with centroid-centroid distances of 3.651 (2) and 3.721 (2) Å. The crystal studied was a non-merohedral twin with a refined minor component of 20.1 (3)%.

Project description:The title compound, C(20)H(16)N(4)O(4), contains two crystallographically independent mol-ecules (A and B) in the asymmetric unit.
