Figure 3: Orientation of the main magnetic axes in the ground Kramers’ doublets.
From: Influencing the properties of dysprosium single-molecule magnets with phosphorus donor ligands

(a) For 2-Dy. (b) For 3-Dy. The magnetic axes are represented as dashed red lines. The dysprosium centres are represented as green spheres and the phosphorus atoms as orange spheres.
