Figure 3. Magnetochemical characterization of 3.

(a) Temperature dependence of magnetic moment for the crystalline sample of 3. The solid line represents the best fit obtained with the parameters given in the text. (b) Field-dependent magnetization measurements at variable temperature (as M_mol versus B/T) for the crystalline sample of 3. Simulation of the experimental data with the use of the spin Hamiltonian and taking into account zero-field and Zeeman splitting (equation (1)) resulted in the following parameters values: g=2.05 and D=+20.7 cm⁻¹.
