Specific features of the formation of diffraction patterns of metallofullerene crystals

The specific features of the formation of diffraction patterns of face-centered cubic crystals of metallofullerene clathrates have been investigated. It has been demonstrated that the presence of dopants in holes of fullerite crystals substantially affects the ratio between the X-ray reflection intensities. The regularities in the redistribution of the intensities of diffraction peaks when metal atoms fill interstices and intramolecular cavities of the face-centered cubic fullerite crystal have been established.
