Lanthanide complexes of 2,2 ',2 ''-(10-{[Hydroxy(phenyl)phosphoryllmethyll}-1,4,7,10-tetraazacyclododecan-1,4,7-triyl)triacetic acid: Structural characterisation of intermediates from the complexation mechanism in the systems of Ln(III)-dota-Type Ligands

Abstract

The structures of ten lanthanide complexes of H(4)do3aP(Ph) are presented .The complexes constitute a new type of coordination compounds within the Lndota family. They represent an intermediate stage on the way from the ligand to the in-cavity complexes.
