A third polymorph of N,N′-bis­(pyridin-2-yl)benzene-1,4-diamine

A third polymorph of the title compound, C(16)H(14)N(4), has been obtained. The mol­ecule adopts a non-planar conformation with an E configuration at the two partially double exo C N bonds of the 2-pyridyl­amine units. Like in the triclinic form [Bensemann et al. (2002 ▶). New J. Chem. 26, 448–456],...

description A third polymorph of the title compound, C(16)H(14)N(4), has been obtained. The mol­ecule adopts a non-planar conformation with an E configuration at the two partially double exo C N bonds of the 2-pyridyl­amine units. Like in the triclinic form [Bensemann et al. (2002 ▶). New J. Chem. 26, 448–456], the recognition process between 2-pyridyl­amine units takes place through formation of a cyclic R (2) (2)(8) hydrogen-bond motif, leading to the creation of tapes parallel to [001].
