3-(4-Chloro-phen-yl)-1-(4-nitro-phen-yl)benzo[f]quinoline.

ABSTRACT: In the title compound, C(25)H(15)ClN(2)O(2), the pyridine ring is inclined at angles of 6.89 (7), 4.24 (9) and 66.98 (4)° with respect to the naphthalene, chloro-phenyl and nitro-phenyl rings, respectively. The two substituent aromatic rings make a dihedral angle of 71.1 (1)° with one another. C-H⋯π and π-π stacking are present in the crystal structure; the π-π stacking [centroid-centroid distance between the pyridyl rings of adjacent mol-ecules= 3.7838 (11) Å] links the mol-ecules into dimers, while the C-H⋯Cg type π-ring inter-actons link the mol-ecules into a chain structure along c.

2-Chloro-N-[2-(2-fluoro-benzo-yl)-4-nitro-phen-yl]-N-methyl-acetamide.

Project description:The title compound, C(16)H(12)ClFN(2)O(4), crystallizes with two mol-ecules in the asymmetric unit in which the dihedral angles between the mean planes of the two benzene rings are 65.1 (7) and 65.6 (6)°. In each mol-ecule, the nitro group displays rotational disorder over two orientations in a 0.503 (11):0.497 (11) ratio and the Cl atom is disordered in a 0.432 (5):0.568 (5) ratio. In one mol-ecule, the F atoms is statistically disordered over two positions. The crystal packing features weak inter-molecular C-H⋯O and C-H⋯Cl inter-actions, which form a layered network.

2-Ferrocenyl-6-(3-nitro-phen-yl)quinoline.

Project description:In the title compound, [Fe(C5H5)(C20H13N2O2)], the substituted cyclo-penta-dienyl ring and quinoline system are approximately coplanar, making a dihedral angle of 5.18 (6)°, while the dihedral angle between the quinoline system and the benzene ring is 28.45 (8)°. There is high thermal motion in the free cyclo-penta-dienyl ring compared with the substituted cyclo-penta-dienyl ring. The conformation of the two cyclopentadienyl rings in the ferrocenyl moiety is eclipsed.

2-Chloro-N-[4-chloro-2-(2-chloro-benzo-yl)phen-yl]acetamide.

Project description:In the title compound, C(15)H(10)Cl(3)NO(2), an intra-molecular N-H?O hydrogen bond forms a six-membered ring and enforces an almost coplanar conformation for the acetamido group, the central benzene ring and the bridging carbonyl C-C(=O)-C group: the dihedral angles between the benzene ring and the acetamide and carbonyl C-C(=O)-C planes are 7.06?(11) and 7.17?(12)°, respectively. The dihedral angle between the two benzene rings is 67.43?(9)°. Because a strong hydrogen-bond donor is involved in the intra-molecular inter-action, the crystal packing is determined by weak C-H?O and C-H?Cl inter-actions.

1-(3-Chloro-phen-yl)-3-(4-nitro-phen-yl)urea.

Project description:In the title compound, C(13)H(10)ClN(3)O(3), prepared by the reaction of 1-chloro-3-isocyanato-benzene with 4-nitro-benzenamine, the two substituent benzene rings are roughly coplanar [inter-ring dihedral angle = 8.70?(7)°]. In the crystal, mol-ecules make cyclic inter-molecular associations through two urea-nitro N-H?O hydrogen bonds, forming a chain structure [give chain direction] in which there are also weak inter-molecular C-H?Cl inter-actions. The urea O atom has only intra-molecular aromatic ring C-H?O associations.

The fused-ring system is buckled owing to the ethyl-ene linkage in the central ring. There are two independent overlapped mol-ecules in the asymmetric unit. In one independent mol-ecule, the two flanking aromatic rings are twisted by 24.4?(1)° and the ring of the chloro-phenyl substituent is twisted by 87.3?(1)° relative to the amino- and cyano-bearing aromatic ring. In the second mol-ecule, the respective dihedral angles are 26.1?(1) and 57.8?(1)°. The two independent mol-ecules are linked by N-H?N hydrogen bonds into dimers.
