摘要：
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(sic)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].
