The asymmetric unit of the title compound, C(10)H(8)center dot 2C(16)H(14)N(4), 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 center dot center dot center dot N hydrogen bonds between the PDAB molecules generate a cyclic R(2)(2)(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.
