摘要：

Synthesis of [Ru-2(O2CH)(4)](3)[M-III(CN)(6)] (M = Co, Fe) possessing an interpenetrating body center cubic (bcc) lattices was investigated utilizing several synthetic methods. The targeted interpenetrating bcc [a = 12.6621(3) angstrom] structure was obtained for [Ru-2(O2CH)(4)](3)[Co(CN)(6)], and it exhibits chi T(T) that is fit to a model which includes zero field splitting. Cyanide abstraction from [Cr(CN)(6)](3-) occurs thwarting the formation of [Ru-2(O2CH)(4)](3)[M(CN)(6)].[Ru-2(O2CH)(4)](3)[Fe(CN)(6)] also exhibits the desired bcc structure [12.7071(3) angstrom], and its 13.4 K T-c is a 6-fold enhancement with respect to that observed for [Ru-2(O2CMe)(4)](3)[Fe(CN)(6)].
