Structure and Dynamics of Lanthanide Complexes of Triethylenetetramine-N,N,N',N...
Zitha-Bovens, Emrin; Muller, Robert N.; Laurent, Sophie; Vander Elst, Luce; Geraldes, Carlos F. G. C.; van Bekkum, Herman; Peters, Joop A.A multinuclear NMR study on [Ln(ttha)]3- and [Lnttha(NHR)2]- complexes (R=Et, CH2(CHOH)4CH2OH) shows that coordinating groups of the organic ligands in these complexes are occupying all coordination sites of the metal ions, leaving no space for coordination of H2O molecules (H6ttha=triethylenetetramine-N,N,Nprime,NPrime,Nprimeprimeprime,Nprimeprimeprime-hexaacetic acid). The lanthanides of the first half of the...
Lanthanide(III) Complexes of Novel Mixed Carboxylic-Phosphorus Acid Derivatives...
Kotek, Jan; Lebduscaronková, Petra; Hermann, Petr; Elst, Luce Vander; Muller, Robert N.; Geraldes, Carlos F. G. C.; Maschmeyer, Thomas; Lukescaron, IvanThree novel phosphorus-containing analogues of H5DTPA (DTPA = diethylenetriaminepentaacetate) were synthesised (H6L1, H5L2, H5L3). These compounds have a -CH2-P(O)(OH)-R function (R = OH, Ph, CH2NBn2) attached to the central nitrogen atom of the diethylenetriamine backbone. An NMR study reveals that these ligands bind to lanthanide(III) ions in an octadentate fashion through the three nitrogen atoms, a P-O oxyg...
