Hydrogen-bonded Lamellar Network of Pyromellitic Acid Pillared by 8-Hydroxyquinoline
Abstract
8-Hydroxyquinoline (8-q) salt of pyromellitic acid (benzene-1,2,4,5-tetracarboxylic acid, H4bta) forms robust lamellar structure where [H2bta]2− anions build up sheets through strong hydrogen bonds in two dimensions and [H-8-q]+ cations act as pillars to afford an extended three dimensional network.
