Coordination chemistry of 3- and 4-mercaptobenzoate ligands: Versatile hydrogen-bonding isomers of the thiosalicylate (2-mercaptobenzoate) ligand
This review summarises the coordination chemistry of the isomeric 3- and 4-mercaptobenzoate ligands, derived from HSC6H4COOH, being isomers of the widely-studied 2-mercaptobenzoate (thiosalicylate) ligand. The 3- and 4-mercaptobenzoate ligands show a wide range of coordination modes, including mo...

| description | This review summarises the coordination chemistry of the isomeric 3- and 4-mercaptobenzoate ligands,
derived from HSC6H4COOH, being isomers of the widely-studied 2-mercaptobenzoate (thiosalicylate)
ligand. The 3- and 4-mercaptobenzoate ligands show a wide range of coordination modes, including
monodentate (through either S or less commonly O), chelation through the carboxylate group alone, as
well as a wide range of bridging modes. However, S,O-chelation, which is prevalent for thiosalicylate
complexes, is not found in the 3MBA and 4MBA isomers. In the solid-state, complexes of 3MBA and
4MBA ligands containing protonated carboxylic acid groups typically undergo aggregation through formation
of classical hydrogen-bonded carboxylic acid dimer motifs, which can be supplemented by additional
interactions such as aurophilic (Au� � �Au) interactions in the case of gold(I) complexes. The hybrid
hard-soft nature of 3MBA and 4MBA ligands facilitates the use of these ligands in the construction of
early-late heterobimetallic complexes. These ligands also find numerous applications (such as the protection
of metallic gold and silver nanoparticles), which are especially prevalent for 4MBA where the para
carboxylate/carboxylic acid group is remote from the sulfur coordination site. |
