2,2'-Bis(1-ethylbenzimidazol-2-yl)biphenyl

R. T. Stibrany, H. J. Schugar and J. A. Potenza

Abstract: The title compound, C₃₀H₂₆N₄, adopts a folded, twisted clamshell geometry in the solid state in which the ethyl groups are trans, and in which the imidazole fragments of the benzimidazole units are nearly eclipsed. Distances between imidazole fragments indicate extensive intramolecular - interactions. The molecules pack in columns along b with little, if any, intermolecular - interactions. In contrast, the n-propyl analog, 2,2'-bis(1-propylbenzimidazol-2-yl)]biphenyl, adopts an extended conformation with little, if any, - interactions of any kind.
