Synthesis and Structural Characterization of a Cyano-bridged Dinuclear Dysprosium (III) -Iron (III) Complex [ DyFe ( CN )6 (DMF)4 (H2O)3 ]·1.25H2O

A dinuclear complex [DyFe(CN)6(DMF)4(H2O)3] @ 1.25H2O (DMF = N, N-dimethylformamide) 1 based onthe cyanide as linkage was prepared and structurally characterized by X-ray single-crystal structure analysis. TheDy (Ⅲ) ion is eight coordinations in a square-antiprism arrangement and the Fe (Ⅲ) ion is six coordinations orientedoctahedrally. The neutral units [DyFe(CN)6(DMF)4(H2O)3] are held together by hydrogen bonds formed by latticewater molecules, coordinated water molecules and nitrogen atoms of cyanide coming from other distinct complexunits to afford a three-dimensional framework.
