Benzene Rings

The title compound, C14H12FNO, crystallizes as thetransphenol–imine tautomer. The two benzene rings are essentially coplanar, being inclined to one another by 9.28 (7)°. This is at least in part due to the intramolecular O—H...N hydrogen bond between the hydroxy O atom and the imine N atom. The crystal structure is stabilized by an array of weak C—H...O and C—H...F interactions, which link the molecules into a stable three-dimensional network.

In the title compound, C9H9N3OS, the plane of the benzene ring forms a dihedral angle of 33.40 (5)° with that of the triazole group. In the crystal, molecules are linked by O—H...N hydrogen bonds involving the phenol –OH group and one of the unsubstituted N atoms of the triazole ring, resulting in chains along [010]. These chains are further extended into a layer parallel to (001) by weak C—H...N hydrogen-bond interactions. Aromatic π–π stacking [centroid–centroid separation = 3.556 (1) Å] between the triazole rings links the layers into a three-dimensional network.
