ACS AuthorChoice - This is an open access article published under a Creative Commons Attribution (CC-BY) License., High-field electron paramagnetic resonance spectroscopy shows that the structurally distorted MnIII ion in Na5[Mn(l-tart)2]·12H2O (1; l-tart = l-tartrate) has a significant negative axial zero-field splitting and a small rhombic anisotropy (∼1% of D). Alternating-current magnetic susceptibility measurements demonstrate that 1, which contains isolated MnIII centers, displays slow relaxation of its magnetization under an applied direct-current magnetic field., The U.K. Engineering and Physical Sciences Research Council are thanked for financial support (Grant EP/K033662/1). Work performed at the NHMFL was supported by the NSF (Grants DMR-1157490 and DMR-1309463) and the State of Florida.
