The mol-ecule of the title compound, C(13)H(11)NO, is almost planar (r.m.s. deviation = 0.013 Å), apart from the cyanide group, for which the C and N atoms deviate from the mean plane of the other atoms by 0.341 (3) and 0.571 (4) Å, respectively. In the crystal, weak aromatic π-π stacking [centroid-centroid distance = 3.758 (3) Å] may help to stabilize the structure.
