2,6-Bis[1-(2-isopropyl-phenyl-imino)-ethyl]-pyridine.

ABSTRACT: The title compound, C(27)H(31)N(3), has E substitution at each imine double bond where the two N atoms adopt a trans-trans relationship. The benzene rings are twisted out of the mean plane of the pyridine ring; the mean planes of the aromatic groups are rotated by 63.0 (1) and 72.58 (8)°. The crystal structure is sustained mainly by C-H⋯π and hydro-phobic methyl-methyl inter-actions.
