title: 4,4'-Butane-1,4-diylbis[3-ethyl-1H-1,2,4-triazol-5(4H)-one] and 4-hydroxy-3-n-propyl-1H-1,2,4-triazol-5(4H)-one.
abstract: The title compounds, C12H20N6O2, (I), and C5H9N3O2, (II), display the characteristic features of 1,2,4-triazole derivatives. Compound (I) lies about an inversion centre which is at the mid-point of the central C-C bond. Compound (II) also contains a planar 1,2,4-triazole ring but differs from (I) in that it has a hydroxy group attached to the ring. Molecules of (I) are held together in the crystal structure by intermolecular N-H...O contacts and by weak pi-pi stacking interactions between the 1,2,4-triazole moieties. Compound (II) contains intermolecular O-H...O and N-H...O hydrogen bonds.
