The melting diagram of the system pyridine-hydrogen chloride was determined by DTA. It reveals the existence of intermediary solid complexes pyridine · xHCl with x = 0.5, 1, 2, 4 and 6. The structures of those with x = 1 (room-temperature phase), 2, 4 and 6 were determined from single-crystal MoKa diffractometer data at low temperatures. Pyridinium and chloride ions and, with the exception of the mono-adduct, hydrogen chloride molecules are hydrogen-bonded into various discrete molecular and complex-ionic structural units. Among these are the first poly-(hydrogen chloride) anions, H n Cl n+1  -  or [Cl(HCl) n ] -  with n &amp;gt; 1 (viz. n = 2, 4 and 5), characterized by crystal structure analysis.
