N,N'-Bis(4-bromo-phen-yl)pyridine-2,6-dicarboxamide.

ABSTRACT: The mol-ecule of the title compound, C19H13Br2N3O2, lies about a twofold rotation axis. The benzene ring makes dihedral angles of 8.9?(2) and 16.4?(2)° with the central pyridine ring and the second benzene ring, respectively. An intra-molecular N-H?N contact occurs. In the crystal, mol-ecules are connected by pairs of N-H?O hydrogen bonds into chains along the c axis.

The mol-ecule of the title compound, C19H13Br2N3O2, lies about a twofold rotation axis. The benzene ring makes dihedral angles of 8.9 (2) and 16.4 (2)° with the central pyridine ring and the second benzene ring, respectively. An intra-molecular N-H⋯N contact occurs. In the crystal, mol-ecules are connected by pairs of N-H⋯O hydrogen bonds into chains along the c axis. ...[more]

Project description: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).

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.

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.

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.

Two N,N'-bis-(pyridin-4-yl)pyridine-2,6-dicarboxamide coordination compounds.

Project description:The molecular structures of tetra-aqua-[N,N'-bis-(pyridin-4-yl)pyridine-2,6-dicar-boxamide]-sulfatomanganese(II) dihydrate, [Mn(SO4)(C17H13N5O2)(H2O)4]·2H2O or [Mn(H2L1)(SO4)(H2O)4]·2H2O, (I), and tetra-aqua-bis[N,N'-bis-(pyridin-4-yl)pyridine-2,6-dicar-boxamide]cadmium(II) sulfate tetra-hydrate, [Cd(C17H13N5O2)2(H2O)4]SO4·4H2O or [Cd(H2O)4(H2L1)2]·SO4·4H2O, (II), both contain a central metal atom in a distorted octa-hedral geometry coordinated equatorially by four oxygen atoms from water mol-ecules. In (I), the axial positions are occupied by a nitro-gen atom from H2L1 and an oxygen atom from the sulfate anion, whereas in (II), the axial positions contain two nitro-gen atoms from two different H2L1 ligands and the sulfate anion acts as the charge-balancing ion. ?-? stacking between pyridine rings and a network of hydrogen bonds involving the water molecules and the sulfate anions play a crucial role in the mol-ecular self-assembly of the two structures.

4-Bromo-N,N,N,N-tetra-ethyl-pyridine-2,6-dicarboxamide.

Project description:The title compound, C(15)H(22)BrN(3)O(2), consists of a pyridine ring with a bromine atom in the para position and two diethyl-amide groups in the ortho positions of the ring. Despite the positions of the three substituents on the pyridine ring, the mol-ecule does not exhibit either local or crystallographic twofold symmetry as the two diethyl-amido units exhibit significantly different N(py)-C-C-N(am) torsion angles of 46.3?(4) and 62.7?(4)° (py is pyridine and am is amine). Inter-molecular C-H?O inter-actions support the packing.

The packing also features C-H?O and C-H?N hydrogen bonds and C-H?? interactions, one directed to the benzene ring and the other to the center of the pyridine ring.
