The first direct observation of pentachlorocyclopentadienyl cation (C5Cl5+) by IR spectroscopy was made in cryogenic SbF5 matrix. The structure of the ion, analyzed by DFT calculations, was found to have D5h symmetry. It was found that the stabilizing effect of chlorine lone pair electrons, which was observed in other α-chlorocarbocations (CCl3+ or C3Cl3+), is not present in this molecule.
