Abstract

The first monocarboxylate-substituted 4, 4′-bipyridine ligand, 4, 4′-bipyridine-2-carboxylic acid (4-(pyridin-4-yl) pyridine-2-carboxylic acid (PPCAH)), has been successfully synthesized from 4, 4′-bipyridine. Reactions with transition metals zinc and manganese were used to establish the coordination characteristics of the product, 4, 4′-bipyridine-2- carboxylic acid, and of the synthetic intermediate, 2-methyl-4, 4′-bipyridine, by single- ...
