Abstract | Full Text

In the title compound, C18H14NSe+·HSO4−, the cyclopentene ring in the cation has an envelope conformation while the central six-membered 1,4-selenazine ring adopts a sofa conformation. The dihedral angle between the planes of the terminal benzene rings is 68.08 (11)°. In the crystal, the anions form chains along the c axis through O—H...O hydrogen bonds. Weak C—H...O and C—H...π hydrogen bonds, as well as attractive Se...Se [3.5608 (8) Å] interactions, further consolidate the crystal structure.
