N2 - Complexes of trivalent lanthanides are utilized in medicine and preclinical research as magnetic resonance, optical or nuclear probes. In this contribution, thermodynamic (ligand dissociation and complex stability constants) and kinetic (formation and dissociation) properties of selected lanthanide(III) complexes with phosphorus-containing macrocyclic ligand which are based on cyclen skeleton will be presented. The ligands are H8dotp analogs where substituents modified on all parent phosphonate groups are monoester (H4dotpOEt), phosphinate (H4dotpH) or phenylphosphinate (H4dotpPh). The H8dotp analogs are less basic then the mother ligand and, consequently, the thermodynamic stabilities of the lanthanide(III) complexes are much lower. Rates of the complex formation of studied ligands are of the same order of magnitude to that for H8dotp. Kinetic inertness of complexes of the anologs is mostly lower; however, the kinetic inerteness is still much higher than that of complexes of open-chain ligands.
