(S,S)-1,2-Bis(1-methylbenzimidazol-2-yl)-1',2'-bis(methoxy)ethane

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

Abstract: The title compound, C₂₀H₂₂N₄O₂, exhibits twofold site symmetry and adopts a stepped or kinked conformation in the solid state, with the approximately planar N-methyl benzimidazole fragments corresponding to the run and the 1',2'-bis(methoxy)ethane fragment to the rise. When viewed along the b axis, the molecules stack in a herringbone pattern as layers along a. Intermolecular distances suggest that the molecules are held in the lattice largely by C-H interactions with little, if any, bonding. Examination of the displacement parameters suggests that the molecules librate about axes approximately parallel to the a axis and passing near the center of mass of the molecules. Bond distances in the imidazole group lie within one s.u. of the average reported for 19 structures containing comparable benzimidazole fragments.
