Abstract

Kinetically inert and yet catalytically active is the lanthanum complex 1, whereas the analogous Eu and Dy complexes catalyze neither cleavage of RNA oligomers nor transes‐terification of a phosphate diester. A possible explanation for the different behavior is the size of the La³⁺ ion, which enables an expansion of the coordination sphere from nine to ten. (Figure Presented.)
