The atomic and crystal structure of a single crystal is studied over a broad temperature range by means of x-ray structural analysis. The relative "rigidity" of the atomic triad Ol-Cul-ΟΓ is determined on the basis of an analysis of the change in the thermal vibrations of atoms and the atomic spacing.
