Popis: Three new 1D cyanido-bridged 3d-4f coordination polymers, {[Gd(L)(H2O)2Fe(CN)6]·H2O}n(1GdFe), {[Dy(L)(H2O)2Fe(CN)6]·3H2O}n(2DyFe), and {[Dy(L)(H2O)2Co(CN)6]·H2O}n(3DyCo), were assembled following the building-block approach (L = pentadentatebis-semicarbazone ligand resulting from the condensation reaction between 2,6-diacetyl-pyridine and semicarbazide). The crystal structures consist of crenel-like LnIII-MIIIalternate chains, with the LnIIIions connected by the hexacyanido metalloligands through twociscyanido groups. The magnetic properties of the three complexes have been investigated. Field-induced slow relaxation of the magnetization was observed for compounds2DyFeand3DyCo. Compound3DyCois a new example of chain of Single Ion Magnets.
