The conformational equilibrium of the title compound has been investigated experimentally in the gas phase by gas electron diffraction and in solution at low temperatures by 13C NMR, and theoretically by quantum chemical calculations. Both experimental methods result in a preference of the equatorial position of the methyl group, 68(7) % in the gas phase at 298 K and 74(1) % in solution at 110 K. The calculations predict 66 % equatorial conformer at room temperature.
