Physico-chemical properties of MnII complexes formed with cis- and trans-DO2A: thermodynamic, electrochemical and kinetic studies

MnII complexes formed with cis- and trans-DO2A chelators have been investigated by pH-potentiometry, 1H relaxometry, UV-vis spectrophotometry and cyclic voltammetry. The physico-chemical characteristics of MnII complexes of these structure isomers do not differ dramatically, however the cis-DO2A platform has better potential for further development owing to its coordinated water molecule.106
