- Abstract
- In this contribution, the solid-state low-temperature phase structure of [2,2]-paracyclophane is unambiguously characterised by single-crystal X-ray analysis. Additionally, a heat capacity measurement was undertaken, which proves the existence of a -type phase transition at 45K, a transition that is connected with the formation of a secondary Cp/T feature at 60K. The low-temperature phase (<45K) crystallises in the lower symmetry space group P$\bar 4, whereas the high-temperature phase (>60K) crystallises in space group P42/mnm. This proves what has been postulated both by experimental and theoretical chemists but has repeatedly been dismissed as speculation many times.
