N2  - The pentachlorobenzoates, NaOCOC6Cl5,2H2O, KOCOC6Cl5,H2O, MOCOC6Cl5 (M = Cs or Tl), Hg(OCOC6Cl5)2, RHgOCOC6Cl5 (R = Ph or p-MeOC6H4), and R3SnOCOC6Cl5 (R = Ph or Me) have been prepared by neutralization, metathesis, or cleavage reactions. Vibrational assignments have been made for infrared absorption frequencies of, these compounds, pentachlorobenzoic acid, bispenta-chlorophenylmercury, and pentachlorophenylmercuric chloride. The carboxylate stretching frequencies indicate that Hg(OCOC6Cl5)2, RHgOCOC6Cl5, and R3SnOCOC6Cl5 (in chloroform) have unidentate pentachlorobenzoate ligands, whereas crystalline R3SnOCOC6Cl5 compounds have bridging pentachlorobenzoate groups. Pentachlorobenzoic acid is dimeric in the solid state, and in toluene, carbon tetrachloride, and benzene there are both monomeric and dimeric species.
