Abstract

Time-domain synchrotron Mössbauer spectroscopy (SMS) based on the Mössbauer effect of <superscript>161</superscript> Dy has been used to investigate the magnetic properties of a Dy <superscript>III</superscript> -based single-molecule magnet (SMM). The magnetic hyperfine field of [Dy(Cy <subscript>3</subscript> PO) <subscript>2</subscript> (H <subscript>2</subscript> O) <subscript>5</subscript> ]Br <subscript>3</subscript> ⋅2 (Cy <subscript>3</subscript> PO)⋅2 H <subscript>2</subscript> O⋅2 EtOH is with B <subscript>0</subscript> =582.3(5) T significantly larger than that of the free-ion Dy <superscript>III</superscript> with a <superscript>6</superscript> H <subscript>15/2</subscript> ground state. This difference is attributed to the influence of the coordinating ligands on the Fermi contact interaction between the s and 4f electrons of the Dy <superscript>III</superscript> ion. This study demonstrates that <superscript>161</superscript> Dy SMS is an effective local probe of the influence of the coordinating ligands on the magnetic structure of Dy-containing compounds.<br /> (© 2019 Wiley-VCH Verlag GmbH & Co.
