Figure 8
Projection of the pseudocell showing one of the two molecular orientations (effective space group R3 rather than R3m). The locations of the symmetry elements within one unit cell are shown. Three sets of the two short Cl⋯Cl contacts are marked. Note that the Δz values for the contacts involving the Cl2 atoms have the opposite sign from the Δz values for the contacts involving the Cl1 and Cl3 atoms. In projection the two sets of contacts seem to involve the same pair of molecules, but the contacts actually involve a molecule in one stack and two molecules in an adjacent stack.
