摘要

Mononuclear Co(II) complexes of the [CoCl₂L₂] family, with L being a heterocyclic N-donor ligand, were subjected to magnetochemical investigation. The temperature dependence of the magnetic susceptibility and the field dependence of the magnetization have been analyzed simultaneously in terms of the spin Hamiltonian formalism. The magnetic parameters obtained by a fitting procedure show a considerable magnetic anisotropy measured by the g-factor difference and the zero-field splitting parameter 2D, that splits the ground term ⁴B₁(D_2d) and/or ⁴A₂(C_2v).
