Single crystals of type I clathrate K 8Zn 4Sn 42 and K 8In 8Sn 38 were grown by the flux method. The structure properties of both clathrates were investigated by single-crystal x-ray diffraction. Both clathrates crystallize in space group Pm3 ¯ n, and no phase transition was observed in the investigated temperature range (100 K–450 K). The Debye temperature, the Einstein temperature, and the static disorder parameters of each clathrate were derived. The spread of the Einstein temperatures for K 8In 8Sn 38, K 8Zn 4Sn 42, and K 8In 8Sn 38 suggest that the charge distribution on the cage framework is crucial to the energy of rattling mode in the tetrakaidecahedron of the type-I clathrate.
