Abstract
[Ru<sub>2</sub>Mn(O)(O<sub>2</sub>C<i>t</i>Bu)<sub>6</sub>(py)<sub>3</sub>] has an S=5/2 ground state with a very large zero-field splitting (ZFS) of <i>D</i>=2.9 cm<sup>−1</sup>, as characterized by EPR spectroscopy at 4–330 GHz. This is far too large to be due to the Mn<sup>II</sup> ion (<i>D</i> <0.2 cm<sup>−1</sup>), as shown from the {Fe<sub>2</sub>Mn} analogue, but can be modeled by antisymmetric exchange effects.
