Abstract

Two cyanide-bridged bimetallic assemblies, [Mn(en)]₃ [Cr(CN)₆]₂· 4H₂O (1) (en=ethylenediamine) and [Mn(glya)]₃[Cr(CN)₆]₂· 2.5H₂O (2) (glya=glycine amide), have been obtained. X-ray crystallographic studies indicate that they have a three-dimensional network structure based on a defective cubane unit. Magnetic studies demonstrate that both are ferrimanget with T_c=69 K for 1 and 71 K for 2. Remnant magnetizations for 1 and 2 are 1.2×10⁴ and 1.1×10⁴ cm³ G mol^-1, respectively, and coercive fields are 28 and 19 G, respectively. The assemblies 1 and 2 are relevant to a Prussian blue analogue, Mn₃[Cr(CN)₆]₂·12H₂O, which is also a ferrimagnet with T_c=63 K, a remnant magnetization of 3.1×10³ cm³ G mol^-1 and a coercive field of 8 G.
