The experimental values of heat capacity and thermal expansion for lutetium boride LuB66 in the temperature range of 2–300 K were analysed in the Debye–Einstein approximation. It was found that the vibration of the boron sub-lattice can be considered within the Debye model with high characteristic temperatures; low-frequency vibration of weakly connected metal atoms is described by the Einstein model.
