The Versatility of Ethylene Glycol to Tune the Dimensionality and Magnetic Properties in Dy-Anilato-Based Single-Ion Magnets.

We exploit the high versatility of the solvent ethylene glycol (eg = CHOH-CHOH) acting as a ligand with three different coordination modes: terminal (κ), chelate (κ), and bridge (1κ,2κ) to prepare a novel family of six different coordination polymers with Dy and three different anilato ligands (3,6-disubstituted-2,5-dihydroxy-1,4-benzoquinone dianion = COX, with X = H, Cl, and Br). With the X = H derivative (dhbq), we have prepared [Dy(dhbq)(eg)(μ-eg)]·4eg·2HO (), a 3D diamond-like network with a chelate and bridging eg molecules. With the X = Cl derivative (chloranilato), we have prepared [Dy(COCl)(eg)]·2eg·HO () and [Dy(COCl)(μ-eg)(HO)]·2eg·7HO ().
