The title compound, CHN, which crystallizes in the monoclinic 2/ 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 [(H7⋯) = 2.7391 (2) Å], forming cyclic centrosymmetric dimers, further resulting in an infinite one-dimensional linear chain along the -axis direction. Weak face-to-face π-π stacking inter-actions [(⋯) = 3.6061 (2) Å] link neighboring lamellar networks into the supra-molecular structure.
标题化合物CHN以单斜2/空间群结晶，不对称单元中有半个分子，通过9-溴蒽与吡啶-4-硼酸的铃木-宫浦交叉偶联反应合成，并通过硅胶柱色谱法纯化。通过溶剂蒸发法收集了适合X射线衍射的4-(蒽-9-基)吡啶浅黄色晶体。在晶体中，分子对通过分子间C-H⋯π（吡啶）相互作用[（H7⋯）= 2.7391 (2) Å]相连，形成环状中心对称二聚体，进而沿轴方向形成无限的一维线性链。弱的面对面π-π堆积相互作用[（⋯）= 3.6061 (2) Å]将相邻的层状网络连接成超分子结构。
