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)] . 1.25H(2)O (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 (III) ion is eight coordinations in a square-anti prism arrangement and the Fe (111) 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.
