title: 1,2-Di-2-quinolylethene.
abstract: The title compound, C(20)H(14)N(2), comprises two crystallographically independent centrosymmetric mol-ecules (A and B) with different conformations due to the disorder of molecule B. The whole of mol-ecule B is disordered over two sets of positions, corresponding to a 180° rotation of the molecule, with a site-occupancy ratio of 0.780 (6):0.220 (6). The minor component of the disordered part in B has the same configuration as mol-ecule A, but the major component is different. The dihedral angle between the planes of mol-ecule A and mol-ecule B (major component) is 63.22 (3)°. The crystal structure is stabilized by inter-molecular C-H⋯π inter-actions.
