High Magnetization Reversal Barriers in Luminescent Dysprosium Octahedral and Pentagonal Bipyramidal Single-Molecule Magnets based on fluorinated alkoxides ligands.

We report the synthesis and structures of three luminescent dysprosium(III) complexes based on fluorinated alkoxide ligands of formulas [Dy(L1)2(THF)4][BPh4]•0.5THF (1), [Dy(L2)2(THF)5][BPh4]•2.5THF (2) and [Dy(L3)2(THF)5][BPh4]•2THF (3) (L1 = (CF3)3CO-, L2 =...

Synthesis and crystal structure of [Zn6Br4(C9H18NO)4(OH)4]·2C3H6O2

The complete molecule of the hexametallic title complex, namely, tetrabromidotetra-μ-hydroxido-hexakis[μ-2-methyl-3-(pyrrolidin-1-yl)propan-2-olato]hexazinc(II) acetone disolvate, [Zn6Br4(C9H18NO)4(OH)4]·2C3H6O2, is generated by a crystallographic centre of symmetry. Two of the unique zinc atoms adopt distorted ZnO2NBr tetrahedral coordination geometries and the other adopts a ZnO3N tetrahedral arrangement. Both unique alkoxide ligands are N,O-chelating and both hydroxide ions are μ2 bridging. The crystal structure displays an O—H...O hydrogen bond between a μ2-OH group and an acetone solvent molecule. The Hirshfeld surface has been calculated and is described.
