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

ABSTRACT: In the title compound, C(12)H(11)ClN(2), the dihedral angle between the benzene and pyridyl rings is 48.03?(8)°. Twists are also evident in the mol-ecule, in particular about the N(a)-C(b) (a = amine and b = benzene) bond [C-N-C-C = -144.79?(18)°]. In the crystal, inversion dimers linked by pairs of N-H?N hydrogen bonds result in the formation of eight-membered {?NCNH}(2) synthons [or R(2) (2)(8) loops].

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].

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].

Tetra-?-acetato-?O:O'-bis-{[N-(4-chloro-phen-yl)-4-methyl-pyridin-2-amine-?N]copper(II)}.

Project description:In the crystal structure of the title complex, [Cu(2)(CH(3)COO)(4)(C(12)H(11)ClN(2))(2)], the complete binuclear mol-ecule is generated by a crystallographic centre of inversion; the four acetate groups each bridge a pair of Cu(II) atoms. The coordination of the metal atom is distorted octa-hedral within a donor set defined by four O atoms, the heterocyclic N atom and the second Cu atom. The pyridine ring is twisted with respect to the benzene ring, forming a dihedral angle of 33.9?(2)°. An intra-molecular N-H?O hydrogen bond is present between the amino group and a carboxyl O atom. Inter-molecular inter-actions of the C-H?? type link mol-ecules in the crystal structure.

4-(4-Chloro-phen-yl)-6-(methyl-sulfan-yl)pyrimidin-2-amine.

Project description:In the title compound, C(11)H(10)ClN(3)S, the dihedral angle between the benzene and pyrimidine rings is 3.99?(4)°. In the crystal, inter-molecular N-H?N hydrogen bonds link the mol-ecules into ribbons of R(2) (2)(8) rings parallel to [100]. Weak C-H?S contacts connect adjacent ribbons into a two-dimensional undulating layer-like structure extending parallel to (110). The benzene and pyrimidine rings of adjacent mol-ecules have the offset face-to-face ?-? stacking inter-actions in a zigzag fashion along the c axis, with perpendicular ring distances of 3.463 and 3.639?Å, and a dihedral angle between the planes of 3.99?(2)°. The distance between the ring centroids is 4.420?(2)?Å.

Project description:The five-membered ring of the title compound, C(11)H(9)ClF(3)N(3), is almost planar (r.m.s. deviation = 0.002 Å) and the phenyl-ene ring is aligned at 44.8 (1)°. The N atom of the amino substituent shows a pyramidal geometry and is a hydrogen-bond donor to a Cl atom and to a ring N atom, which together generate a layer motif.

An intra-molecular N-H?N hydrogen bond stabilizes the mol-ecular conformation. In the crystal, N-H?O hydrogen bonds link the mol-ecules into inversion dimers. These dimers are connected by ?-? inter-actions between imidazole rings [shortest centroid-centroid distance = 3.4443?(14)?Å].

The dimers are linked via C-H?? interactions forming chains along [101].

Project description: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 ?-? 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].
