Abstract

original image

Using 57Fe Mössbauer spectroscopy, three examples of coordination compounds with different topologies containing FeIII and LnIII ions (DyIII and TbIII; see diagram; insets: clusters cores) were analyzed. In the same crystal field environment, Dy and Tb ions show different degrees of anisotropy, which can be qualitatively detected using an indirect method.
