Headphones In the title compound, C26H32N4, the essentially planar (r.m.s.deviations of 0.0053 and 0.
0242 Å) benzimidazole fragments are trans with respect to a central ethene fragment, and are canted in opposite directions by 2.78 (6) and 5.87 (6)° with respect to the ethene plane, giving the molecule a propeller conformation.The terminal ethyl fragments of the pendant n-propyl groups protrude to either side of the benzimidazole planes.Overall, the molecule exhibits a pseudo-center of symmetry at the mid-point of the ethene fragment.
Both π–π stacking and typical C—H.π interactions are notably absent, as are intermolecular hydrogen bonds.When viewed along Wall Shelf (Set of 3) the a axis, the structure appears as criss-crossed layers of molecules with the planar fragments separated along the c-cell direction by the protruding ethyl groups.
