The title compound (C16H15N3O2, Mr = 281.31) has been synthesized and characterized by elemental analysis and single-crystal X-ray diffraction. The Schiff base compound is a derivative of 4-aminoantipyrine. As expected, the molecular structure adopts a trans configuration about the C=N double bond. It crystallizes in the monoclinic system, space group P21/c with a = 11.150(3), b = 9.906(3), c = 13.624(4) ?, β = 106.360(4)°, V = 1443.9(7) ?3, Z = 4, Dc = 1.294 g/cm3, F(000) = 592, μ(MoKα) = 0.088 mm-1, R = 0.0577 and wR = 0.1214. Of the 5766 total reflections, 2540 were unique. In the molecule there exist two different planes of pyrazoline and O(2)～C(10) phenyl ring, which are appro- ximately coplanar (r.m.s. de deviation from the combined mean plane is 0026 ?) with the dihedral angle between them of 6.3°.
