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 π–π stacking interactions between the 1,2,4‐triazole moieties. Compound (II) contains intermolecular O—H⋯O and N—H⋯O hydrogen bonds. |
