1-Phenyl-isatin

In the title compound, C(14)H(9)NO(2), the phenyl ring makes a dihedral angle of 50.59 (5)° with the mean plane of the isatin fragment. In the crystal, mol-ecules are linked through weak inter-molecular C-H⋯O hydrogen bonds. The crystal structure also exhibits two slipped π-π inter-actions between the benzene rings of neighbouring mol-ecules [centroid-centroid distance = 3.968 (3) Å, inter-planar distance = 3.484 (3) Å and slippage = 1.899 (3) Å], and between the phenyl rings of neighbouring mol-ecules [centroid-centroid distance = 3.968 (3) Å, inter-planar distance = 3.638 (3) Å and slippage = 1.584 (3) Å].
