title: (E)-1,2-Bis(1-allyl-benzimidazol-2-yl)ethene.
abstract: In the title compound, C(22)H(20)N(4), the two benzimidazole ring systems are nearly coplanar [dihedral angle = 4.70 (5)°]. Two terminal C atoms of one allyl group are disordered over two sites of equal occupancy. The crystal structure is stabilized by π-π stacking inter-actions, the centroid-centroid distance between nearly parallel [dihedral angle = 19.82 (4)°] benzene and imidazole rings being 3.7885 (15) Å.
