4-(4-Nitro-benz-yl)morpholine.

ABSTRACT: In the title compound, C(11)H(14)N(2)O(3), an inter-molecular inter-action between a nitro group O atom and a neighboring benzene ring helps to stabilize the crystal structure [N⋯centroid = 3.933 (2) Å]. No classical hydrogen bonds are observed in the crystal packing.

N-(4-Methyl-benz-yl)-3-nitro-anilinium chloride.

Project description:The cation of the title compound, C(14)H(15)N(2)O(2) (+)·Cl(-), comprises two almost ideally planar systems, 3-nitro-phenyl (r.m.s. deviation = 0.0117 Å) and 4-methyl-phenyl (r.m.s. deviation = 0.238 Å), separated by the central C-N bond, and with their mean planes inclined to one another by 61.36 (5)°. In the crystal, hydrogen-bonded chains running along [001] are generated by connecting neighbouring mol-ecules via N-H⋯Cl hydrogen bonds and consolidated by C-H⋯Cl and C-H⋯O inter-actions. Within these chains, fused R(2) (1)(6) and R(3) (2)(10) ring motifs are formed. Parallel chains are further linked into a two-dimensional network parallel to (100) via C-H⋯O inter-actions.

N-(4-Fluoro-benz-yl)-3-nitro-pyridine-2,6-diamine.

Project description:In the title compound, C(12)H(11)FN(4)O(2), the pyridine ring is connected to a benzene ring by a -CH(2)-NH(2)- chain. The nitro group is twisted out of the pyridine ring plane [torsion angle O-N-C-C = 10.41?(10)°]. An intramolecular N-H?O hydrogen bond occurs. The fluoro-benzene ring is disordered over two positions [occupancy ratio = 0.59?(3):0.41?(3)]. Inter-molecular N-H?O and N-H?N hydrogen bonds stabilize the crystal structure.
