Abstract
The first direct observation of pentachlorocyclopentadienyl cation (C5 Cl5+) by IR spectroscopy was made in cryogenic SbF5 matrix. The struct ure of the ion, analyzed by DFT calculations, was found to have D-5h s ymmetry. It was found that the stabilizing effect of chlorine lone pai r electrons, which was observed in other alpha-chlorocarbocations (CCl 3+ or C3Cl3+), is not present in this molecule.
