[Ru 2 Mn(O)(O2 CtBu)6(py)3]具有S=5/2的基态,具有非常大的零场分裂(D 0),D=2.9 cm(-1),如通过EPR光谱在4-330 GHz处表征的。  这太大了,不能归因于Mn(II)离子(D <0.2 cm(-1)),如{Fe 2 Mn}类似物所示,但可以通过反对称交换效应来建模。 
[Ru2Mn(O)(O2CtBu)6(py)3] has an S=5/2 ground state with a very large zero-field splitting (ZFS) of D=2.9 cm(-1), as characterized by EPR spectroscopy at 4-330 GHz. This is far too large to be due to the Mn(II) ion (D <0.2 cm(-1)), as shown from the {Fe2Mn} analogue, but can be modeled by antisymmetric exchange effects.
