Abstract

The complex [Dy(L)(tta)3] with L the chiral 3-(2-pyridyl)-4-aza[6]-helicene ligand (tta = 2-thenoyltrifluoroaacetonate) has been synthesized in its racemic form and structurally and magnetically characterized. [Dy(L)(tta)3] behaves as a single molecule magnet in its crystalline phase with the opening of a hysteresis loop at 0.50 K. These magnetic properties were interpreted with ab initio calculations.
