Bis{2-[(Tri­phenyl­meth­yl)amino]­phen­yl} diselenide aceto­nitrile monosolvate

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-H...Se hydrogen bonds are noted. Inter­molecular C-H...Se inter­actions give rise to supra­molecular chains extended along [100]. 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.
