摘要：

Phase transition in C-60-dimethoxymethane and C-60-1-bromobutane clathrates were studied by X-ray powder diffraction. Both clathrates show phase transitions corresponding to orientational ordering. Although the two high temperature structures have very similar orthorhombic lattice the phase transitions take place in different ways. In the C-60-dimethoxymethane sample there is no symmetry change while in the C-60-1-bromobutane an orthorhombic to monoclinic transformation of the lattice can be observed.
