| Abstract: | A novel cyanide-bridged bimetallic assembly, Cu(1,3-Pn)2]2FeIII(CN)6]ClO4 · 2H2O (1,3-Pn = 1,3-diaminopropane), derived from Fe(CN)6]3– building blocks and four-coordinated bisdiamine metal(II) ions Cu(1,3-Pn)2]2+ is described and characterized by X-ray crystal analysis. The compound contains a two-dimensional network structure extended through FeIII—CN—Cu linkages. Mössbauer experimental results indicate that the iron is ferric (Fe3+) in the complex. Cryomagnetic measurements reveal an antiferromagnetic exchange interaction between the nearest paramagnetic metal ions in the compound. The exchange mechanism was also discussed. |
