The asymmetric unit of the title compound, C10H8·2C16H14N4, consists of one molecule of N,N′-bis(pyridin-2-yl)benzene-1,4-diamine (PDAB) and one half of the centrosymmetric naphthalene molecule. The PDAB molecule adopts a non-planar conformation with an E configuration at the two partially double exo C...;N bonds of the 2-pyridylamine units. In the crystal, N—H...N hydrogen bonds between the PDAB molecules generate a cyclic R22(8) motif, leading to the formation of PDAB tapes extending along [100]. The tapes are arranged into (010) layers and the naphthalene molecules are enclosed in cavities formed between the PDAB layers.
