The coordination chemistry of cyclohexanepolycarboxylate ligands. Structures, conformation and functions

This review gives an overview on the coordination chemistry of eight cyclohexanepolycarboxylic acids, i.e. cyclohexanecarboxylic acid, 1,2-, 1,3- and 1,4-cyclohexanedicarboxylic acid, 1,3,5- and 1,2,4-cyclohexanetricarboxylic acid, 1,2,4,5-cyclohexanetetracarboxylic acid and 1,2,3,4,5,6-cyclohexanehexacarboxylic acid, and explores their possible applications in materials science, especially as magnetic materials. The conformational transformation of cyclohexanepolycarboxylic acids in the presence of various metal ions under hydrothermal conditions is included and the α-proton removal mechanism is discussed as well.
