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 the ions Gd3+, Tb3+ and Dy3+ results in a family of compounds that features 1D-chains that crystallize in the Pmmn space group. [Fe(CN)6]3– couple with trinu- clear complexes containing Gd3+ - Er3+ yields a family of compounds featuring 2D-networks that crystallize in the Pnma space group. Using [Co(CN)6]3 – , a new family of compounds character- ized by 1D-chains is obtained when the trinuclear cluster has the ions Ho3+, Er3+ and Y3+, which crystallize in the Pnma. Magnetic susceptibility and magnetization measurements of selected compounds shows a magnetically independent behavior of their constituting ions with exception of C30H54N12O9Er3Fe.
