title: N,N'-Bis-[(E)-(6-methyl-2-pyridyl)-methyl-ene]hexane-1,6-diamine.
abstract: The title compound, C(20)H(26)N(4), is composed of two (6-methyl-2-pyridyl)methyl-ene units linked by a 1,6-diamine hexane chain. The mol-ecule has C(i) symmetry with the inversion center situated at the mid-point of the central C-C bond. The alkyl chain has an all-trans conformation, with all the non-H atoms sharing the same plane [maximum deviation 0.004 (3) Å]. The pyridylmethyl-ene groups are also planar [maximum deviation 0.009 (3) Å], making an angle of 53.78 (19)° with the hexane chain plane. In the crystal, the mol-ecules assemble in layers, stacking along the a axis. The stacks are hold together by attractive interactions between π electron systems.
