In the racemic title compound, C19H14N2OS, the two phenyl substituents on the 1,3-thia-zine ring are almost perpendicular to the pyridine ring which is fused to the thia-zine ring [inter-ring dihedral angles = 87.90 (8) and 85.54 (7)°]. The dihedral angle between the two phenyl rings is 75.11 (7)°. The six-membered thia-zine ring has an envelope conformation with the ortho-related C atom forming the flap. The crystals exhibit face-to-edge aromatic-ring interactions with the nearest C-H⋯C distance equal to 3.676 (3) Å.
在消旋标题化合物C₁₉H₁₄N₂OS中，1,3-硫氮杂环上的两个苯基取代基几乎垂直于与硫氮杂环稠合的吡啶环[环间二面角 = 87.90 (8) 和85.54 (7)°]。两个苯环之间的二面角为75.11 (7)°。六元硫氮杂环具有信封式构象，邻位相关的C原子形成瓣。晶体表现出面-边芳香环相互作用，最近的C—H⋯C距离等于3.676 (3) Å。
