Reactions of cobalt(ii) chloride and cobalt(ii) acetate with hemisalen-type ligands: ligand transformation, oxidation of cobalt and complex formation. Preliminary study on the cytotoxicity of Co(ii) and Co(iii) hemisalen complexes

Dependent on the cobalt precursor, hemisalen complexes tend to transform into polycyclic compounds or bind to the metal ion to form coordination complexes of diverse nuclearity.
