In the title compound, C(24)H(19)N(3)O, the pyrazoline ring adopts an envelope conformation with the C atom linking to the pyridine ring as the flap. The mean plane of the pyrazoline ring makes dihedral angles of 85.54 (4) and 81.66 (3)° with the pyridine ring and the anthracene ring system, respectively. In the crystal, mol-ecules are linked by C-H⋯O hydrogen bonds. In addition, weak π-π inter-actions [centroid-centroid distances = 3.695 (3)-3.850 (7) Å] are observed.
在标题化合物C₂₄H₁₉N₃O中，吡唑啉环呈信封式构象，与吡啶环相连的C原子为折叶。吡唑啉环的平均平面与吡啶环和蒽环体系的二面角分别为85.54 (4)°和81.66 (3)°。在晶体中，分子通过C—H⋯O氢键相连。此外，还观察到弱的π-π相互作用[质心-质心距离 = 3.695 (3)-3.850 (7) Å]。
