4-[2-(4-Hy-droxy-phen-yl)eth-yl]-3-propyl-1H-1,2,4-triazol-5(4H)-one

Abstract

The asymmetric unit of the title compound, C13H17N3O2, 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)degrees. The eight molecules in the asymmetric unit are linked by intermolecular O-H center dot center dot center dot O and N-H center dot center dot center dot O hydrogen bonds, forming a three-dimensional network.
