Abstract
More than 20 new compounds derived from 2,4,6-trihydroxybenzoic acid (H4thba) have been synthesized, with structures that include discrete molecular units and chains, in addition to two- and three-dimensional nets. Intramolecular hydrogen bonds between the ortho-hydroxy groups and the carboxylate group in the H3thba− anion confer a rigid geometry upon the ligand which, when combined with the low basicity of the carboxylate group, limits the variety of metal-binding modes.
