چکیده
In the title compound, C(11)H(8)ClN(3)O(2), the presence of intra-molecular N-H⋯O and C-H⋯N inter-actions help to establish an almost planar mol-ecule [dihedral angle between the pyridine and benzene rings = 9.89 (8)° and r.m.s. deviation for all 17 non-H atoms = 0.120 Å]. Supra-molecular tapes feature in the crystal packing whereby dimeric aggregates sustained by pairs of C-H⋯O inter-actions are connected by π-π inter-actions occurring between translationally related pyridine rings and between translationally related benzene rings along the b axis [centroid-centroid distance = length of b axis = 3.8032 (4) Å].

The dihedral angle between the benzene and pyridyl rings in the title compound, C(11)H(8)ClN(3)O(2), is 22.65 (10)°, indicating a twisted mol-ecule. The amine H and nitro O atoms form a donor-acceptor pair for an intra-molecular N-H⋯O hydrogen bond so that the nitro group is almost coplanar with the pyridine ring to which it is connected [O-N-C-C torsion angle = 7.4 (3)°]. The pyridine N and Cl...

The title mol-ecule, C(5)H(4)ClN(3)O(2), possesses mirror symmetry, with all of the atoms lying in the mirror plane. There is an intra-molecular N-H⋯O hydrogen bond involving the adjacent -NO(2) and -NH(2) groups. A short C-H⋯O inter-action is also observed. In the crystal, adjacent mol-ecules are linked via N-H⋯Cl and N-H⋯N hydrogen bonds, forming chains propagating along [100].

In the title compound, C(6)H(7)N(3)O(2), the dihedral angle between the nitro group and the pyridine ring is 15.5 (3)° and an intra-molecular N-H⋯O hydrogen bond occurs. In the crystal, inversion dimers linked by two N-H⋯N hydrogen bonds occur, resulting in R(2) (2)(8) rings. The packing is stabilized by aromatic π-π stacking [centroid-centroid distance = 3.5666 (15) Å] and a short N-O⋯π contac...

Two independent mol-ecules comprise the asymmetric unit of the title compound, C(12)H(11)N(3)O(2). These differ in terms of the relative orientations of the benzene rings as seen in the respective dihedral angles formed between the pyridine and benzene rings [17.42 (16) and 34.64 (16)°]. Both mol-ecules are twisted about the amine-tolyl N-C bonds [respective torsion angles = 22.3 (5) and 35.9 (...
