1,3-Bis(3-phenyl­prop­yl)-1H-benzimidazol-3-ium-2-carbodithio­ate

The title compound, C(26)H(26)N(2)S(2), was synthesized from bis­[1,3-bis­(3-phenyl­prop­yl)benzimidazolidine-2-yl­idene] and CS(2) in toluene. The mol­ecular structure is composed of a benzimidazole ring system with two phenyl­propyl substituents and a dithio­carboxyl­ate group in the 2-position. The benzimidazole unit is essentially planar, with a maximum atomic deviation of 0.008 (2) Å, and makes dihedral angles of 72.72 (10) and 27.62 (12)°, with the two phenyl rings. The dihedral angle between the two phenyl rings is 55.98 (15)°. The mol­ecular packing is stabilized by a C—H⋯S inter­molecular hydrogen-bonding inter­action and a C—H⋯π inter­action between a benzene H atom and the phenyl ring of a neighbouring mol­ecule.
