A hexanuclear dysprosium(III) compound constructed by two Dy3 triangles in an edge-to-edge arrangement perfectly retains a nonmagnetic ground state and single-molecular-magnet behavior. Such an arrangement and the strong couplings over a μ4-O2− ion stabilize a similar arrangement of toroidal moments in the ground state, thus maximizing the toroidal moment of the complex.
