3-Methoxy-4-methyl-1H-1,2,4-triazol-5(4H)-one monohydrate

Abstract

In the title hydrate, C4H7N3O2·H2O, all the non-H atoms lie on a crystallographic mirror plane. The H atoms of both methyl groups are disordered over two sets of sites. In the crystal, N—H⋯Ow and Ow—H⋯Ok (w = water and k = ketone) hydrogen bonds link the components into (010) sheets.
