Crystal structure of 2-chloro-N-(3-fluorophenyl)acetamide
In the title compound, C8H7ClFNO, the F atom is disordred over the meta positions of the benzene ring in a 0.574 (4):0.426 (4) ratio and the Cl atom is syn to the O atom [O-C-C-Cl = 5.6 (3)°]. A short intra-molecular C-H⋯O contact occurs. In the crystal, mol-ecules are linked into amide C(4) chains propagating in [101] by N-H⋯O hydrogen bonds.

The naphthoquinone ring is almost perpendicular [dihedral angle 71.02 (3)°] to the phenyl group of the title compound, C(17)H(9)Cl(2)NO(3), while the dihedral angle between the amide group and the 4-chloro-phenyl ring is 21.9 (2)°. The conformation of the N-H and C=O bonds are anti to each other. N-H⋯Cl hydrogen bonds link the mol-ecules into chains in the a-axis direction. In addition, these c...
متن کاملCrystal structure of 3-bromomethyl-2-chloro-6-(dibromomethyl)quinoline
In the title compound, C11H7Br3ClN, the quinoline ring system is approximately planar (r.m.s. = 0.011 Å). In the crystal, mol-ecules are linked by C-H⋯Br inter-actions forming chains along [10-1]. The chains are linked by C-H⋯π and π-π inter-actions involving inversion-related pyridine rings [inter-centroid distance = 3.608 (4) Å], forming sheets parallel to (10-1). Within the sheets, there are...

In the title compound, C14H14ClNO4, the dihedral angle between the quinoline ring system (r.m.s. deviation = 0.0142 Å) and ester planes is 18.99 (3)°. The C-O-C-Cm (m = meth-yl) torsion angle is -172.08 (10)°, indicating a trans conformation. In the crystal, the mol-ecules are linked by C-H⋯O and C-H⋯N inter-actions, generating layers lying parallel to (101). Aromatic π-π stacking [centroid-cen...

In the title compound, C13H12ClNO2, the dihedral angle between the planes of the quinoline ring system (r.m.s. deviation = 0.029 Å) and the ester group is 54.97 (6)°. The C-O-C-Cm (m = meth-yl) torsion angle is -140.62 (16)°. In the crystal, mol-ecules inter-act via aromatic π-π stacking [shortest centroid-centroid separation = 3.6774 (9) Å] generating (010) sheets.
