Abstract: The molecular structure of the title compound, C50H40N2Se2·C2H3N, shows a syn conformation of the benzene rings bound to the Se atoms, with an Se-Se bond length of 2.3529 (6) Å and a C-Se-Se-C torsion angle of 93.53 (14)°. The two Se-bonded aromatic ring planes make a dihedral angle of 18.42 (16)°. Intramolecular N-HSe hydrogen bonds are noted. Intermolecular C-HSe interactions give rise to supramolecular chains extended along . One severely disordered acetonitrile solvent molecule per asymmetric unit was treated with SQUEEZE in PLATON [Spek (2009). Acta Cryst. D65, 148-155]; the crystal data take the presence of this molecule into account.
