We report the synthesis and crystal structures of four dysprosium(III) complexes based on the amino-bis(benzotriazole phenolate) ligand (C1NNBiBTP-H2). Whereas a pentagonal bipyramid complex [Dy(C1NNBiBTP-H)Cl2DMF]•THF (1•THF) is obtained in the absence...

Block Approach

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 = pentadentate bis-semicarbazone ligand resulting from the condensation reaction between 2,6-diacetyl-pyridine and semicarbazide). The crystal structures consist of crenel-like LnIII-MIII alternate chains, with the LnIII ions connected by the hexacyanido metalloligands through two cis cyanido groups. The magnetic properties of the three complexes have been investigated. Field-induced slow relaxation of the magnetization was observed for compounds 2DyFe and 3DyCo. Compound 3DyCo is a new example of chain of Single Ion Magnets.

Magnetic Features

In the five ZnII2LnIII2 compounds – (i) the TbIII and ErIII analogues show slow relaxation of the magnetization, while the HoIII system and, surprisingly, the DyIII analogue don’t; (ii) the GdIII system shows the MCE; and (iii) interestingly, the Ln–O bond length increases with the increase of atomic number.
