2-(Phenyl­selenon­yl)pyridine

In the title compound, C₁₁H₉NO₂Se, the pyridine and phenyl rings are almost perpendicular, with the dihedral angle between their mean planes being 79.16 (7)°. In the crystal, the mol­ecules pack so as to form ruffled sheets in the (110) plane connected by weak C—H...O inter­actions. In addition, there are weak π–π inter­actions between the mean planes of both the phenyl [centroid–centroid perpendicular distance of 3.591 (2) Å and slippage of 1.854 (2) Å] and pyridine rings [centroid–centroid perpendicular distance of 3.348 (2) Å and slippage of 1.854 (2) Å].
