The magnetic relaxation processes of dinuclear DyIII-Pc triple-decker complexes (1–3) with the same distance between the two DyIII ions are quite different. Therefore, we clarified the relationship among the coordination environment, the ground state, and the magnetic relaxation processes. In the Zeeman diagram for 1 with D4d symmetry, levels intersect in an Hdc of 2500 Oe, and dual magnetic relaxation processes occur. However, in the case of the dinuclear DyIII-Pc systems (2 and 3) with C4 geometry, which have a twist angle (ϕ) of less than 45°, dual magnetic relaxation processes do not occur. More information can be found in the Full Paper by K. Katoh et al. (DOI: 10.1002/chem.201703945).
