4-Methyl-3-nitro-pyridin-2-amine.

ABSTRACT: 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 ?-? stacking [centroid-centroid distance = 3.5666?(15)?Å] and a short N-O?? contact is seen.

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 contact is seen. ...[more]

2-Chloro-5-nitro-pyridin-4-amine.

Project description: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].

6-Methyl-pyridin-2-amine.

Project description:In the title mol-ecule, C6H8N2, the endocyclic angles are in the range 118.43?(9)-122.65?(10)°. The mol-ecular skeleton is planar (r.m.s. deviation = 0.007?Å). One of the two amino H atoms is involved in an N-H?N hydrogen bond, forming an inversion dimer, while the other amino H atom participates in N-H?? inter-actions between the dimers, forming layers parallel to (100).

Project description:In the mol-ecule of the title compound, C(6)H(8)N(2), the methyl C and amine N atoms are 0.021?(2) and 0.058?(2)?Å from the pyridine ring plane. In the crystal structure, inter-molecular N-H?N hydrogen bonds link the mol-ecules.

N-(4-Methyl-phen-yl)-3-nitro-pyridin-2-amine.

Project description: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?(5)°] but only about the amine-pyridine N-C bond in the first independent mol-ecule [respective torsion angles = -11.7?(5) and 0.8?(5)°]. Intra-molecular N-H?O hydrogen bonds preclude the amine H atoms from forming significant inter-molecular inter-actions. The crystal packing features inter-molecular C-H?O and C-H?? and ?-? [centroid-centroid distance: pyridine-benzene = 3.6442?(19)?Å and pyridine-pyridine = 3.722?(2)?Å] contacts.

3,5-Dichloro-6-methyl-pyridin-2-amine.

Project description:In the title compound, C(6)H(6)Cl(2)N(2), intra-molecular N-H?Cl and C-H?Cl contacts generate five-membered rings, producing S(5) ring motifs. Pairs of inter-molecular N-H?N hydrogen bonds link neighbouring mol-ecules into dimers with R(2) (2)(8) ring motifs. In the crystal structure, these dimers are connected by N-H?Cl inter-actions and are packed into columns.

4-Methyl-N-(3-methyl-phen-yl)pyridin-2-amine.

Project description:The title amine, C(13)H(14)N(2), is twisted with a dihedral angle between the rings of 60.07?(9)°. The amine N-H group and pyridine N atom are syn allowing for the formation of centrosymmetric eight-membered {?HNCN}(2) synthons via N-H?N hydrogen bonds. The two-mol-ecule aggregates are sustained in the three-dimensional crystal packing via C-H?? and ?-? inter-actions [centroid-centroid distance for pyridyl rings = 3.7535?(12)?Å].

6-Ethyl-N-methyl-3-nitro-4-nitro-methyl-4H-chromen-2-amine.

Project description:In the title compound, C(13)H(15)N(3)O(5), the O and N atoms of the nitro-methyl group and the methyl C atom of the ethyl group are disordered over two sets of sites with refined occupancies of 0.629?(7):0.371?(7) and 0.533?(8):0.467?(8), respectively. The dihydro-pyran ring has an extremely flattened conformation. An intra-molecular N-H?O hydrogen bond occurs. In the crystal, pairs of N-H?O hydrogen bonds link mol-ecules, forming inversion dimers. In addition, weak inter-molecular C-H?O hydrogen bonds are also present.

6,8-Dichloro-N-methyl-3-nitro-4-nitro-methyl-4H-chromen-2-amine.

Project description:In the title compound, C(11)H(9)Cl(2)N(3)O(5), the dihydro-pyran ring adopts a near-half-chair conformation. The benzene ring makes a torsion angle of 5.02 (5)° with the dihydro-pyran ring. Adjacent mol-ecules are inter-linked through inter-molecular C-H⋯O, N-H⋯O and C-Cl⋯π [3.4743 (9) Å] inter-actions. The inter-molecular N-H⋯O hydrogen bond generates an R(2) (2)(12) motif, which is observed to contribute to the crystal packing stability. Moreover, the mol-ecular structure displays an S(6) motif formed by intra-molecular N-H⋯O hydrogen bonding.

N-(3-Chloro-phen-yl)-3-nitro-pyridin-2-amine.

Project description: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 atoms are approximately syn. The crystal packing features C-H?Cl inter-actions that lead to undulating supra-molecular chains along [101]. These are connected into sheets by ?-? inter-actions occurring between the benzene rings and between the pyridine rings of translationally related mol-ecules along the b axis [centroid-centroid distances = length of b axis = 3.7157?(2)?Å].

Crystal structure of a new monoclinic polymorph of N-(4-methyl-phen-yl)-3-nitro-pyridin-2-amine.

Project description:The title compound, C12H11N3O2, is a second monoclinic polymorph (P21, with Z' = 4) of the previously reported monoclinic (P21/c, with Z' = 2) form [Akhmad Aznan et al. (2010 ?). Acta Cryst. E66, o2400]. Four independent mol-ecules comprise the asymmetric unit, which have the common features of a syn disposition of the pyridine N atom and the toluene ring, and an intra-molecular amine-nitro N-H?O hydrogen bond. The differences between mol-ecules relate to the dihedral angles between the rings which range from 2.92?(19) to 26.24?(19)°. The geometry-optimized structure [B3LYP level of theory and 6-311?g+(d,p) basis set] has the same features except that the entire mol-ecule is planar. In the crystal, the three-dimensional architecture is consolidated by a combination of C-H?O, C-H??, nitro-N-O?? and ?-? inter-actions [inter-centroid distances = 3.649?(2)-3.916?(2)?Å].
