The crystal structure of diphenyl succinate, C t6HNO4, has been solved by direct methods from 1089 reflections collected on a Syntex P1 diffractometer. The final R w value is 0.046. The crystals belong to the space group P2~/c and have a unit cell of dimensions a = 9.096 (3), b = 5.688 (2), c = 13.305 (5) A and fl = 93.26 (2) °. The molecule consists of three planar moieties: the succinate group and the two phenyl groups which are at 67.7 ° from the succinate part of the molecule.
