4-[2-(4-Hydroxyphenyl)ethyl]-3-propyl-1H-1,2,4-triazol-5(4H)-one

The asymmetric unit of the title compound, C13H 17N3O2, contains eight crystallographically independent molecules. The planes of the benzene and triazole rings in the eight molecules make dihedral angles of 5.53 (13), 9.33 (13), 19.28 (11), 17.36 (8), 12.84 (12), 8.03 (8), 19.97 (11), and 7.98 (8)°. The eight molecules in the asymmetric unit are linked by intermolecular O - H⋯O and N - H⋯O hydrogen bonds, forming a three-dimensional network
