Study of the supramolecular interactions of carboxylic acids used as versatile ligands in coordination chemistry

Abstract

Carboxylate ligands are very versatile because they can adopt different coordination modes towards metal cations, such as monodentate, bidentate-chelate, bidentate bridging and monoatomic bridging. Because of this versatility, these ligands have been widely used in coordination chemistry. In this study the three dimensional structure of the crystal arrangement of 2,5-thiophenedicarboxylic (H₂TPD), trans-3-(3- pyridyl)acrylic (HPYA), and 4,4′-sulfonyldibenzoic (H₂SFD) acids are determined in order to investigate their supramolecular properties for coordination polymers and metal-organic framework (MOF) constructions.
