title: 2,2'-[(1E,1'E)-2,2'-(2,5-Dibut-oxy-1,4-phenyl-ene)bis-(ethene-2,1-di-yl)]dipyridine.
abstract: The centrosymmetric title mol-ecule, C(28)H(32)N(2)O(2), has a central benzene ring subsituted in the 1- and 4-positions by (ethene-2,1-di-yl)pyridine groups, and in the 2- and 5-positions by but-oxy groups. The whole mol-ecule is X-shaped and relatively flat, the dihedral angle between the pyridine and the central benzene ring being 11.29 (10)°. In the crystal, neighboring mol-ecules are linked by weak C-H⋯N inter-actions, forming a two-dimensional undulating network.
