5-(2,3-Dichloro-phen-yl)-2-fluoro-pyridine.

ABSTRACT: In the title compound, C(11)H(6)Cl(2)FN, the dichloro-benzene and the 2-fluoro-pyridine rings are oriented at a dihedral angle of 47.73 (3)°. In the crystal, pairs of C-H⋯N inter-actions link the mol-ecules into dimers with R(2) (2)(12) motifs. Mol-ecules are arranged in stacks extending along [100] via π-π inter-actions with a centroid-centroid distance of 3.8889 (3) Å.

Methyl N-(2,3-dichloro-phen-yl)succinamate.

Project description:The asymmetric unit of the title compound, C(11)H(11)Cl(2)NO(3), contains two independent mol-ecules. In both the molecules, the H atoms of the adjacent -CH(2) groups of the acid segments orient themselves away from the amide O and the carbonyl O atoms. The C=O and O-CH(3) bonds of the ester group are in syn positions with respect to each other. In the crystal, the mol-ecules are linked into infinite chains through inter-molecular N-H?O hydrogen bonds.

2,3-Dichloro-pyridine.

Project description:The complete mol-ecule of the title compound, C(5)H(3)Cl(2)N, is generated by crystallographic twofold symmetry, which forces the pyridine N atom and the opposite C-H group to be statistically disordered. In the crystal, weak aromatic ?-? stacking [centroid-centroid separation = 3.805?(4)?Å and slippage = 1.704?Å] leads to [100] stacks of mol-ecules. Short Cl?Cl contacts [3.334?(3)?Å] are also observed.

2,2-Dichloro-N-(2,3-dimethyl-phen-yl)acetamide.

Project description:The conformation of the N-H bond in the title compound, C(10)H(11)Cl(2)NO, is syn to both the 2- and 3-methyl substituents in the aromatic ring, similar to that of the 2-chloro and 3-chloro substituents in 2,2-dichloro-N-(2,3-dichloro-phen-yl)acetamide and the 2-methyl substituent in 2,2-dichloro-N-(2-methyl-phen-yl)acetamide, but in contrast to the anti conformation observed with respect to the 3-methyl substituent in 2,2-dichloro-N-(3-methyl-phen-yl)acetamide. The bond parameters in the title compound are similar to those in 2,2-dichloro-N-phenyl-acetamide and other acetanilides. The mol-ecules of the title compound are linked into chains through N-H?O and C-H?O hydrogen bonding.

4-[2-(4-Fluoro-phen-yl)furan-3-yl]pyridine.

Project description:In the crystal structure of the title compound, C(15)H(10)FNO, the furan ring makes dihedral angles of 40.04?(11) and 25.71?(11)° with the pyridine and 4-fluoro-phenyl rings, respectively. The pyridine ring makes a dihedral angle of 49.51?(10)° with the 4-fluoro-phenyl ring. Non-conventional C-H?F and C-H?N hydrogen bonds are effective in the stabilization of the crystal structure.
