39. Magnetic data of complex 2 can be quantitatively described on the basis of the branch chain model previously developed in Van Kroningsbrug-gen Kahn, O; Nakatani, K.; Pei, Y; Renard, J. P.; Drillon, M.; Legoll, P. Inorg. Chem. 1990, 29, 3325 for a similar ferrimagnetic chain. The Hamilto-nian used in this model accounts for magnetic exchange interactions between magnetic ions but also includes spin-orbit coupling effects together with the local anisotropy parameters of the Co(II) ion, and different Landée factors for each ion (gA ≠ gB). Unfortunately, the proximity of the 3D magnetization ordering transition to the position of the minimum of the xT curve prevents sensible fitting of the model to our experimental data, since 3D effects could not be ignored.
