The crystal structure of 1-(4-methylphenylamino)-2-phenyl-1,2-ethandione-1-oxime (C15H14N2O2) has been determined by X-ray analysis. It crystallizes in the orthorhombic space group Pna21, with unit cell parameters: a = 23.516(3), b = 5.364(3), c = 21.872(3)Å, V = 2758.7(17)Å3, Dc = 1.224 g/cm3, and Z = 8. The crystal structure was solved by direct methods and refined by full-matrix least squares to a final R-value of 0.041 for 2204 observed reflections. There are two independent molecules, A and B. These molecules are linked by intermolecular O-H···N hydrogen bonds.
