A third polymorph of N,N′-bis(pyridin-2-yl)benzene-1,4-diamine
نویسندگان
چکیده
A third polymorph of the title compound, C(16)H(14)N(4), has been obtained. The mol-ecule adopts a non-planar conformation with an E configuration at the two partially double exo C N bonds of the 2-pyridyl-amine units. Like in the triclinic form [Bensemann et al. (2002 ▶). New J. Chem.26, 448-456], the recognition process between 2-pyridyl-amine units takes place through formation of a cyclic R(2) (2)(8) hydrogen-bond motif, leading to the creation of tapes parallel to [001].
