A high-frequency EPR study of magnetic anisotropy and intermolecular interactions of Co(II) ions

Abstract Changing the anion in a crystal lattice induces distinct structural distortions in the [CoS4]2+ core for a family of complexes with the general molecular formula [Co(L1)4]X2, where L1 = thiourea (NH2CSNH2) and X = I (1), Br (2), and [Co(L1)4](SiF6) (3). The magnetic anisotropy (D) for 1–3 was quantitatively determined with a magnitude of −153(2), −168(5) and
