In the title compound, C14H11F3N2O, the two aromatic rings are oriented at a dihedral angle of 70.84 (8)°. The crystal structure displays intermolecular N—H...O and N—H...F interactions.
4,4-Bis(4-methylphenylsulfanyl)-1,1-diphenyl-2-azabuta-1,3-diene
2007
In the title compound, C29H25NS2, both the Cl atoms of the azadiene precursor 4,4-dichloro-1,1-diphenyl-2-azabuta-1,3-diene are replaced by two vicinal S-p-tolyl substituents attached to the terminal C atom of a π-conjugated 2-azabutadiene array. The azadiene chain is planar to within 0.01 Å. One of the phenyl rings seems to be slightly π-conjugated with the azadiene core [dihedral angle 5.1 (2)°].

The 4-fluorophenyl ring makes dihedral angles of 77.91 (7) and 26.93 (8)° with the pyridine and phenyl rings, respectively. The phenyl and pyridine rings are nearly perpendicular, making a dihedral angle of 86.47 (9)°.

3-(2-Fluorophenyl)-6-(phenoxymethyl)-1,2,4-triazolo[3,4-b][1,3,4]thiadiazole
2008
The crystal structure of the title compound, C16H11FN4OS, was synthesized in the course of our studies on 1,2,4-triazolo[3,4-b][1,3,4]thiadiazoles as inhibitors of p38 mitogen-activated protein kinase (MAPK). The three-dimensional data obtained were used to generate a three-dimensional pharmacophore model for in silico database screening. The dihedral angles between the central heterocylic system and the fluorophenyl and phenyl rings are 20.21 (3) and 5.43 (1)°, respectively; the dihedral angle between the two benzene rings is 15.80 (4)°.
