Abstract

There are two nearly identical mol-ecules in the asymmetric unit of the title compound, C(7)H(7)NO. The mol-ecules are nearly planar (r.m.s. deviations of 0.025 and 0.017 Å) and oriented at a dihedral angle of 28.98 (3)°. The two mol-ecules are linked by a C-H⋯O hydrogen bond. In the crystal, weak inter-molecular C-H⋯O hydrogen bonds link the mol-ecules into zigzag chains along the c axis.
