A dinuclear complex [DyFe(CN)6(DMF)4(H2O)3]·1.25H2O (DMF=N, N dimethylformamide) 1 based on the cyanide as linkage was prepared and structurally characterized by X ray single crystal structure analysis. The Dy?ion is eight coordinations in a square antiprism arrangement and the Fe?ion is six coordinations oriented octahedrally. The neutral units [DyFe(CN)6(DMF)4(H2O)3] are held together by hydrogen bonds formed by lattice water molecules, coordinated water molecules and nitrogen atoms of cyanide coming from other distinct complex units to afford a three dimensional framework. CCDC: 192314.
