摘要：

Four crystalline phases were found for 4'-octyloxy-4-cyanobiphenyl, C21H25NO These were square-plate, needle and long parallelepiped crystals, which are all metastable, and a phase found in a commercially available powder specimen which was the most stable. The structures of the needle and long parallelepiped crystals have been determined at room temperature and 243 K, respectively.
