In the title compound, C(25)H(15)ClN(2)O(2), the pyridine ring is inclined at angles of 6.89 (7), 4.24 (9) and 66.98 (4)° with respect to the naphthalene, chloro-phenyl and nitro-phenyl rings, respectively. The two substituent aromatic rings make a dihedral angle of 71.1 (1)° with one another. C-H⋯π and π-π stacking are present in the crystal structure; the π-π stacking [centroid-centroid distance between the pyridyl rings of adjacent mol-ecules= 3.7838 (11) Å] links the mol-ecules into dimers, while the C-H⋯Cg type π-ring inter-actons link the mol-ecules into a chain structure along c.
在标题化合物C₂₅H₁₅ClN₂O₂中，吡啶环相对于萘环、氯苯环和硝基苯环的倾斜角度分别为6.89（7）°、4.24（9）°和66.98（4）°。两个取代芳香环之间的二面角为71.1（1）°。晶体结构中存在C—H⋯π和π - π堆积作用；π - π堆积作用[相邻分子吡啶环之间的质心 - 质心距离 = 3.7838（11）Å]将分子连接成二聚体，而C—H⋯Cg型π - 环相互作用将分子沿c轴连接成链状结构。
