N,N'-Bis[4-(trifluoro-meth-yl)phen-yl]pyridine-2,6-dicarboxamide.

ABSTRACT: In the title mol-ecule, C(21)H(13)F(6)N(3)O(2), the pyridine ring forms dihedral angles of 1.7?(1) and 5.2?(1)° with the two benzene rings. In the crystal structure, inter-molecular N-H?O hydrogen bonds and ??? inter-actions [centroid-centroid distance of 3.628?(3)?Å between aromatic rings] link mol-ecules into stacks along the c axis. The two trifluoro-methyl groups are each rotationally disordered between two orientations, with occupancy ratios of 0.58?(1):0.42?(1) and 0.55?(1):0.45?(1).

In the title mol-ecule, C(21)H(13)F(6)N(3)O(2), the pyridine ring forms dihedral angles of 1.7 (1) and 5.2 (1)° with the two benzene rings. In the crystal structure, inter-molecular N-H⋯O hydrogen bonds and π⋯π inter-actions [centroid-centroid distance of 3.628 (3) Å between aromatic rings] link mol-ecules into stacks along the c axis. The two trifluoro-methyl groups are each rotationally disordered between two orientations, with occupancy ratios of 0.58 (1):0.42 (1) and 0.55 (1):0.45 (1). ...[more]

N,N'-Bis(8-quinol-yl)pyridine-2,6-dicarboxamide.

Project description:In the mol-ecule of the title compound, C(25)H(17)N(5)O(2), the pyridyl ring is oriented at dihedral angles of 8.90 (3) and 28.67 (4)° with respect to the two planar quinolyl ring systems. Intra-molecular N-H⋯N hydrogen bonds result in the formation of four planar five-membered rings, two of which are nearly coplanar with the adjacent quinolyl ring systems.

2,6-Bis(trifluoro-meth-yl)benzoic acid.

Project description:The title compound, C(9)H(4)F(6)O(2), contains two mol-ecules in the asymmetric unit, one of which exhibits disorder in both of its trifluoro-methyl groups. The dihedral angles between the benzene ring and the carboxyl group are 71.5 (2) and 99.3 (2)° in the two independent mol-ecules. The compound exhibits a catemeric structure resulting from inter-molecular O-H⋯O hydrogen bonding between the carboxyl groups.

N,N'-Bis(4-hy-droxy-phen-yl)pyridine-2,6-dicarboxamide di-methyl-formamide monosolvate.

Project description:The mol-ecular structure of the pyridine derivative, C19H15N3O4·C3H7NO, shows almost planar geometry with dihedral angles of 6.9 (1) and 13.4 (1)° between the pyridine ring and the two benzene rings. This conformation is stabilized by two intra-molecular N-H⋯N(pyridine) bonds. In the crystal, strong O-H⋯O(carboxamide) and N-H⋯O(hy-droxy-phen-yl) hydrogen bonds link the mol-ecules, forming a three-dimensional structure. The di-methyl-formamide solvent mol-ecules are not involved in the hydrogen bonding. The structure shows pseudosymmetry, but refinement in the space group Pbcn leads to significantly worse results and a disordered di-methyl-formamide mol-ecule.

Bis{2,6-bis-[(2-hy-droxy-5-methyl-phen-yl)imino-meth-yl]pyridine} monohydrate.

Project description:The title compound, 2C(21)H(19)N(3)O(2)·H(2)O, was synthesized by a Schiff base condensation of 2,6-diformyl-pyridine with 2-amino-4-methyl-phenol in ethanol. In the crystal, two mol-ecules of 2,6-bis-[(2-hy-droxy-5-methyl-phen-yl)imino-meth-yl]pyridine dimer-ize via hydrogen bonding to a water mol-ecule, which lies on a twofold axis. There are also intra-molecular phenol-imine hydrogen bonds. The dimers are further linked via π-π (phen-yl-pyridine) [centroid-centroid distance = 3.707 (2) Å] and π-π edge-to-edge [3.392 (2) Å] inter-actions. The dihedral angles between the central ring and the two pendant rings are 11.46 (8) and 2.06 (8)° while the pendant rings make a dihedral angle of 10.14 (8)°.

2,6-Bis(bromo-meth-yl)pyridine.

Project description:In the title mol-ecule, C7H7Br2N, the C-Br vectors of the bromo-methyl groups extend to opposite sides of the pyridine ring and are oriented nearly perpendicular to its plane. In the crystal, the mol-ecules related by a c-glide-plane operation are arranged into stacks along the c axis, with centroid-centroid distances between neighboring aromatic rings of 3.778?(2)?Å. A short Br?Br contact of 3.6025?(11)?Å is observed within a pair of inversion-related mol-ecules.
