Metal-organic coordination compound comprising cerium(iii)

Abstract

A metal-organic coordination compound, wherein the coordination compound comprises at least one Cerium (III) coordinated by a poly macrocyclic organic ligand having the formula 1-1 wherein n is an integer of at least 3, Y at each occurrence is independently a n-valent group containing 1 to 30 atoms, L at each of its n occurrences is independently a divalent organic group, wherein L has a sequence of at least 3 atoms, preferably at least 5 atoms connecting both Y in case that Y is a cyclic group connected with each L via different ring atoms of Y, wherein L has a sequence of at least 5 atoms connecting both Y in case that Y is connected with each L via the same atom of Y, wherein the poly macrocyclic organic ligand comprises at least three nitrogen atoms.
