The complexation of trisodium (carboxymethoxy)succinate (Na3CMOS) with calcium(II) and with lanthanide(III) cations has been studied using NMR spectroscopy. Structural information has been obtained from lanthanide-induced shifts (LIS), T1 relaxation rate enhancements and vicinal 1H coupling constants. CMOS forms 1:1 and 1:2 complexes in which it mainly acts as a tetradentate ligand via the three carboxylate groups and the ether oxygen. LIS measurements on non-racemic mixtures of Na3CMOS indicate self-association of the Ln(III) complexes at [CMOS]0 > 0.01 M.
