Single crystals of Ba8CoRh6O21, grown out of a potassium carbonate flux, were characterized by single-crystal X-ray diffraction and magnetic measurements. X-ray data were collected in a superspace group approach and solved using the JANA2000 software package. Ba8CoRh6O21 represents the first example of a structurally characterized m = 5, n = 3 member of the A3n+3mA'nB3m+nO9m+6n family of 2H hexagonal perovskite related oxides and contains chains consisting of six consecutive RhO6 octahedra followed by one distorted CoO6 trigonal prism. Magnetic measurements were carried out on large aligned single crystals, and a very large magnetic anisotropy in the magnetic susceptibility, persisting up to room temperature, was observed.
通过碳酸钾助熔剂生长出的Ba8CoRh6O21单晶，采用单晶X射线衍射和磁性测量进行了表征。X射线数据采用超空间群方法收集，并使用JANA2000软件包求解。Ba8CoRh6O21是2H六方钙钛矿相关氧化物的A3n + 3mA'nB3m + nO9m + 6n族中结构表征的m = 5、n = 3成员的首个实例，包含由六个连续的RhO6八面体后跟一个扭曲的CoO6三角棱柱组成的链。对大尺寸取向单晶进行了磁性测量，观察到在磁化率中存在非常大的磁各向异性，这种各向异性一直持续到室温。
