Abstract

The low temperature hysteretic behavior between 40 mK and 4.8 K was obtained for the interpenetrated 3-D structured [Ru2(O 2CMe)4]3[Fe(CN)6]. The unusual constricted hysteretic behavior reported for isomorphous [Ru2(O 2CMe)4]3[Cr(CN)6] was not observed, however, the [Ru2(O2CMe)4]3[Fe(CN) 6] exhibits a single hysteresis loop and a temperature dependence of the coercivity atypical for a ferrimagnetic ordering transition. The 1.06 kOe coercive field is constant below ∼0.3 K, and shows a rapid initial decrease below 1 K, and continues decreasing at a slower rate up to at least 4.8 K. In contrast to [Ru2(O2CMe)4]3[Cr(CN) 6], which has antiferromagnetic coupling of the ferrimagnetic lattices due to the reduced spin on the [FeIII(CN)6] 3-, [Ru2(O2CMe)4] 3[Fe(CN)6] exhibits ferromagnetic coupling of the ferrimagnetic lattices that dominates for [Ru2(O2CMe) 4]3[Fe(CN)6]. © 2013 Elsevier Ltd.
