Single crystals of two new cobaltites, Ba2Co9O14 and Ba3Co10O17, were obtained from the flux of K2CO3 in the temperature range 800-890 degrees C. They crystallize in an intergrowth structure containing perovskite block and CdI2-type layers and can be attributed to the n = 1 and 2 members in a new intergrowth series of cobaltites, Ba(n+1)Co(n)O(3n+3)(Co8O8). Both Ba2Co9O14 and Ba3Co10O17 are metastable and transform into the known 2H-perovskite-related oxides at high temperature.
两种新型钴酸盐Ba2Co9O14和Ba3Co10O17的单晶是在800 - 890摄氏度的K2CO3助熔剂中获得的。它们以包含钙钛矿块和CdI2型层的共生结构结晶，并且可归因于钴酸盐新共生系列Ba(n + 1)Co(n)O(3n + 3)(Co8O8)中的n = 1和2成员。Ba2Co9O14和Ba3Co10O17都是亚稳的，在高温下会转变为已知的与2H - 钙钛矿相关的氧化物。
