Abstract
In the title compound, C12H13NO2, the five-membered ring has an envelope conformation; the disubstituted C atom lies out of the mean plane through the four other ring atoms (r.m.s. deviation = 0.0038 Å) by 0.1877 (18) Å. The plane of the phenyl substituent is practically perpendicular to that of the planar part of the five-membered ring, with a dihedral angle of 87.01 (5)°. In the crystal, mol-ecules are linked by weak C-H⋯O hydrogen bonds, forming inversion dimers. The dimers are linked by further C-H⋯O hydrogen bonds, as well as carbon-yl-carbonyl attractive inter-actions [O⋯C = 3.2879 (19) Å], forming a three-dimensional framework structure.
