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...

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...
متن کاملN′-(2-Methyl-3-phenylallylidene)nicotinohydrazide monohydrate
The asymmetric unit of the title compound, C(16)H(15)N(3)O·H(2)O, contains an N'-(2-methyl-3-phenyl-allyl-idene)nicotino-hydra-zide mol-ecule and a water solvent mol-ecule. The dihedral angle between the pyridine ring and the phenyl ring is 47.26 (5)°. Inter-molecular O-H⋯N, O-H⋯O, N-H⋯O and C-H⋯O hydrogen bonds are found in the crystal structure. Furthermore, C-H⋯π inter-actions involving the ...
متن کاملN-(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. ...
متن کاملN-(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...
