Acta Crystallographica Section C Crystal Structure Communications, 2000
The β modification of pyridinium dichloroiodide, C 5 H 6 N + .Cl 2 I - , was obtained as yellow crystals by the reaction of (C 5 NH 5 )AuCl 3 , C 5 H 6 N + .Cl - and I 2 in a vacuum-sealed ampoule. The dichloroiodide ion is nearly symmetric and linear with I-Cl bond lengths of 2.544 (3) and 2.550 (3) A and a Cl-I-Cl angle of 179.68 (12)°.

Chichibabin pyridinium synthesis

Tetrahedron Letters, 2019
Abstract Chichibabin pyridine synthesis involves the reaction of three aldehydes and ammonia to form 2,3,5-trisubstituted pyridines. This study examined the synthesis of tetrasubstituted pyridinium from aldehydes and an amine hydrochloride in the presence/absence of Pr(OTf)3.

Bis(pyridinium) Pamoate

Acta Crystallographica Section C Crystal Structure Communications, 1996
Attempted crystallization of pamoic acid from its solution in pyridine instead produced the crystalline title compound, bis(pyridinium) 4,4′-methylenebis(3-hydroxy-2-naphthalenecarboxylate), 2C5H6N+.C23H14O62−. In this structure, intramolecular hydrogen bonding involves hydroxyl O atoms as donors and carboxylate O atoms as acceptors, while ...
