1-Phenyl-2-(1H-1,2,4-triazol-1-yl)ethanone

Abstract

In the molecule of the title compound, C10H9N3O, the triazole and phenyl rings are nearly perpendicular to each other, with a dihedral angle of 88.72 (4)°. In the crystal structure, intermolecular C—H...O and C—H...N hydrogen bonds link the molecules. There are C—H...π contacts between the 1,2,4-triazole rings, and between the phenyl and 1,2,4-triazole rings, and there is a weak π–π contact between the 1,2,4-triazole and phenyl rings [centroid-to-centroid distance = 4.547 (1) Å].
