The role of intermolecular H···H and C···H interactions in the ordering of [2.2]paracyclophane at 100 K: estimation of the sublimation energy from the experimental electron density function

The intermolecular interactions responsible for the ordering of the [2.2]paracyclophane molecule in a crystal at 100 K have been found out and their strengths and the lattice energy have been estimated on the basis of a high resolution X-ray diffraction study and plane-wave DFT calculations.
