N-(3-Chloro­phen­yl)-3-nitro­pyridin-2-amine

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...

N-(3-Methyl­phen­yl)pyrimidin-2-amine

Two independent mol-ecules comprise the asymmetric unit in the title compound, C(11)H(11)N(3). These differ in terms of the relative orientations of the aromatic rings: the first is somewhat twisted, while the second is approximately planar [dihedral angles between the pyrimidine and phenyl rings = 39.00 (8) and 4.59 (11)°]. The mol-ecules also form distinct patterns in their hydrogen bonding. ...

N-(4-Chloro­phen­yl)-3-nitro­pyridin-2-amine

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 a...

N-(3-Methyl­phen­yl)quinoxalin-2-amine monohydrate

The quinoxaline system in the title hydrate, C(15)H(13)N(3)·H(2)O, is roughly planar, the r.m.s. deviation for the 18 non-H atoms being 0.188 Å; this conformation features a short intra-molecular C-H⋯N(pyrazine) inter-action. In the crystal, the amine H atom forms an N-H⋯O hydrogen bond to the water mol-ecule, which in turn forms two O-H⋯N hydrogen bonds to the pyrazine N atoms of different org...

N-Benzyl­pyridin-2-amine

In the crystal of the title compound, C(12)H(12)N(2), inter-molecular N-H⋯N hydrogen bonds form rings of graph-set motif R(2) (2)(8) and C-H⋯π inter-actions further consolidate the dimers. Neighbouring dimers are further connected into a three-dimensional network by C-H⋯π inter-actions. The benzyl and pyridyl rings form a dihedral angle of 67.2 (1)°
