    Abstract

    The low temperature hysteretic behavior between 40 mK and 4.8 K was obtained for the interpenetrated 3-D structured [Ru-2(O2CMe)(4)](3)[Fe(CN)(6)]. The unusual constricted hysteretic behavior reported for isomorphous [Ru-2(O2CMe)(4)](3)[Cr(CN)(6)] was not observed, however, the [Ru-2(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 similar to 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 [Ru-2(O2CMe)(4)](3)-[Cr(CN)(6)], which has antiferromagnetic coupling of the ferrimagnetic lattices due to the reduced spin on the [Fe-III(CN)(6)](3-), [Ru-2(O2CMe)(4)](3)[Fe(CN)(6)] exhibits ferromagnetic coupling of the ferrimagnetic lattices that dominates for [Ru-2(O2CMe)(4)](3)[Fe(CN)(6)].
