Crystal structure and Hirshfeld surface analysis of 8-aza-niumylquinolinium tetra-chlorido-zincate(II).

ABSTRACT: The reaction of 8-amino-quinoline, zinc chloride and hydro-chloric acid in ethanol yielded the title salt, (C₉H₁₀N₂)[ZnCl₄], which consists of a planar 8-aza-n-ium-yl-quinolinium dication and a tetra-hedral tetra-chloro-zincate dianion. The 8-amino-quinoline moiety is protonated at both the amino and the ring N atoms. In the crystal, the cations and anions are connected by inter-molecular N-H⋯Cl and C-H⋯Cl hydrogen bonds, forming sheets parallel to (001). Adjacent sheets are linked through π-π inter-actions involving the pyridine and arene rings of the 8-aza-niumylquinolinium dication. Hirshfeld surface analysis indicates that the most important contributions to the crystal packing are from H⋯Cl (48.1%), H⋯H (19.9%), H⋯C/C⋯H (14.3%) (involving th
