Abstract

A technique for calculating magnetic susceptibility of dimeric octahedral Co(II) complexes with a paramagnetic ligand allowing for exchange interactions between dimers is developed within the molecular-field approximation. Model calculations are performed. From an analysis of the experimental data on magnetic susceptibility values of parameters J = 61 cm-1 of intramolecular Ĥexch = - 2JŜCoŜL) and J'n = 4.6 cm-1 and of intermolecular (Ĥ'exch = -2J'nΣŜu 〈Su〉 exchange interactions, ferromagnetic in nature, are determined for a new Co(II) complex compound with a 4-amido-2,2-dimethyl-5,5-dimethoxy-3-imidazoline-1-oxyl radical.
