摘要

The K - C_(60) system was studied using the NMR method. The phase composition of the sample with the empirical formula K_1C_(60) was determined; K_1C_(60), K_3C_(60), a solid solution of K in fullerite C60, and polymer were detected and their amounts were estimated. The maximal content of polymer was not more than 90%. In samples with different contents of K_3C_(60), solid solution, and polymer, the ratio of occupancies of tetrahedral and octahedral sites with potassium was found to be 2 : 1.
