Essaghouani, Abdelhanine published the artcile3-Phenylisoxazolin-5-one: a redetermination, Recommanded Product: 3-Phenylisoxazol-5(2H)-one, the publication is IUCrData (2017), 2(1), x170032, database is CAplus.
The structure of the title mol., C9H7NO2, has been redetermined to improved precision and the H atoms located [Cannas et al. (1969). Acta Crystalline B25, 1050]. The five-membered ring is almost planar (r.m.s. deviation = 0.006 Å) and subtends a dihedral angle of 2.45 (6)° with the benzene ring. In the crystal, mols. form ribbons running parallel to the a-axis direction through a combination of C-H···N and C-H···O hydrogen bonds. ‘Stair-step’ offset π-π stacking interactions are also observed
