(Received 20 January 2010; accepted 20 January 2010; online 27 January 2010)

The imino C=N double bond in the title compound, C14H10N2O, exists in an E conformation, with the phenyl ring being twisted by 80.7 (1)° in one independent mol­ecule and by 81.4 (1)° in the other with respect to the plane of the indoline fused-ring system. The two independent mol­ecules are linked by N—H⋯O hydrogen bonds, forming a zigzag chain running along the a axis.

Experimental top

The compound was synthesized from the reaction of isatin and aniline in ethanol according to a literature method (Grimshaw & Begley, 1974), and crystals were obtained by recrystallization from ethanol.

Refinement top

Carbon-bound H-atoms were placed in calculated positions (C—H 0.93 Å) and were included in the refinement in the riding model approximation, with U(H) set to 1.2U(C). The amino H-atoms were located in a difference Fourier map, and were refined isotropically with a distance restraint of N–H 0.86±0.01 Å. Friedel pairs were merged.
