New coordination networks containing trinuclear lanthanide complexes and hexacyanometallates

Abstract

Three different families of trinuclear lanthanide complexes supported by TDCI (1,3,5-tris(dimethylamino)-1,3,5-trideoxy-cis-inositol), [Ln3(TDCI)2(H2O)6]3+, and hexacyanometallates as linkers have been synthesized and structurally characterized. The combination of [Cr(CN)6]3− and trinuclear complexes having Gd3+, Tb3+ and Dy3+ ions results in a family of compounds that features 1D-chains that crystallize in the Pmmn space group. [Fe(CN)6]3− couples with trinuclear complexes containing Gd3+–Er3+ yielding a family of compounds featuring 2D-networks that crystallize in the Pnma space group. Using [Co(CN)6]3−, a new family of compounds characterized by 1D-chains is obtained when the trinuclear cluster has Ho3+, Er3+ and Y3+ ions, which crystallize in the Pnma space group. Magnetic susceptibility and magnetization measurements of the selected compounds show a magnetically independent behavior of their constituting ions with the exception of C30H54N12O9Er3Fe.
