Synthesis of a hexagonal modification of C60 using cryoextraction Original Research Article

Samples of the hexagonal close-packed phase (h.c.p.) of fullerite C60 with a low (less then 7%) content of more stable face-centered cubic (f.c.c.) phase were synthesized using cryoextraction with n-hexane. X-Ray diffraction analysis and thermogravimetry were applied for characterization of the samples. The role of n-hexane in the formation of the h.c.p. structure is discussed.
