Magnetostructural Study Of Four-Coordinated Co(Ii) Complexes With Mixed Ligand Surrounding

The dependence of the zero-field splitting parameters on the structural modification of the nearest ligands surrounding in the [CoCl2L2] complexes (with L being the N-donor ligand) is studied. The modification was modeled by the variations of the NCoN and ClCoCl angles, by the rotation of the chlorido ligands with respect to other ligand groups as well as by the strength of the N-donor ligands. The found tendency was compared with the experimental data for this type of cobalt complexes known from literature. (C) 2020 Elsevier Ltd. All rights reserved.
