For an fcc crystal prepared by sublimation, there is a sharp hysteretic lambda-shaped anomaly at 260 K, reflecting a latent heat spread over 3 K, similar to what is observed in powders using differential scanning calorimetry. There is also a discontinuity of 11.6R in the specific heat. For orthorhombic crystals prepared by slow evaporation from a toluene-hexane solution, a nonhysteretic, apparently second-order, transition is observed at 239 K. There is a peak in the specific heat consistent with a transition entropy of R ln12.
