Orientational glasses with CO molecules occupying 26 and 90% of the octahedral interstitial sites in the
C₆₀ lattice have been investigated by the dilatometric method in a temperature interval of 2.5–22 K. At temperatures
4–6 K the glasses undergo a first-order phase transition which is evident from the hysteresis of the
thermal expansion and the maxima in the temperature dependences of the linear thermal expansion coefficients
α (T), and the thermalization times τ₁(T) of the samples. The effect of the noncentral CO–C₆₀ interaction
upon the thermal expansion and the phase transition in these glasses was clarified by comparing the behavior
of the properties of the CO–C₆₀ and N₂–C₆₀ solutions.
