Abstract

original image

Easy come, easy go: The first molecular SO2 complexes of the lanthanides (Ln=Sm, Eu) have been prepared. The compounds can reversibly coordinate gaseous SO2. Concomitant with the addition and removal of SO2, the color of the complexes changes reversibly (see scheme). The structures of the SO2 compounds could be confirmed in solution and in the solid state.
