Abstract The molecular structures of chloride salts of 2-and 5-substituted derivatives of 8-
hydroxyquinoline, Me–H 2 Q+· Cl–([C 10 H 10 NO] Cl) and Cl–H 2 Q+· Cl–([C 9 H 7 ClNO]+·
Cl–), were determined by single crystal X-ray diffraction methods; the latter is a new
polymorph. In the crystal structures of these salts, several intra-and inter-molecular
interactions result in a step-shaped centrosymmetric R 4 4 (8) ring. Unlike most quinolinium
salts, there was no solvent present in these structures. Protonation of the quinoline N atom ...
