A simple bridge solves a difficult architectural problem. Ligand H 4 tpaen, with an ethylenediamine backbone that has ten donor atoms, yields ten‐coordinate lanthanide complexes, thus providing highly effective protection of the metal center from interaction with the solvent molecules. As a result, the Eu III and Tb III complexes of (tpaen) 4− show a bright and long‐lived luminescence in H 2 O combined with high solubility and stability.
