Complexation of lanthanoid metal ions with 1,2-bis(oaminophenoxy)-ethane-N,N,",N'-tetraacetic acid and its two derivatives, in which the distance between the chelating functions is changed, has been studied by potentiometric pH titration. There are two complexation modes depending on the size o f th
## Abstract A series of di‐ and tetraamide derivatives of DOTA were synthesized, and their lanthanide(III) complexes were examined by multinuclear ^1^H‐, ^13^C‐, and ^17^O‐NMR spectroscopy, and compared with literature data of similar, known complexes (__Table__). All ligands formed structures simi
The complexes formed by [(1)-2,3-P 2 Mo 2 W 15 O 61 ] 10-with vanadium(IV), manganese(II), cobalt(II), nickel(II), copper(II), and zinc(II) were synthesized. They were characterized by elemental analysis, IR, UV/Vis and 31 P NMR spectroscopy. Their electrochemical studies are complemented by those o
