Abstract
The title compound, C19H13N, which crystallizes in the monoclinic C2/c space group with one half-mol-ecule in the asymmetric unit, was synthesized by Suzuki-Miyaura cross-coupling reaction of 9-bromo-anthracene with pyridin-4-ylboronic acid and purified by column chromatography on silica gel. Light-yellow crystals of 4-(anthracen-9-yl)-pyridine suitable for X-ray diffraction were collected by the solvent evaporation method. In the crystal, pairs of mol-ecules are connected by inter-molecular C-H⋯π (pyridine) inter-actions [d(H7⋯Cg) = 2.7391 (2) Å], forming cyclic centrosymmetric dimers, further resulting in an infinite one-dimensional linear chain along the c-axis direction. Weak face-to-face π-π stacking inter-actions [d(Cg⋯Cg) = 3.6061 (2) Å] link neighboring lamellar networks into the supra-molecular structure.
