8 as oxidant. The influence of the type of Co(II) salt used to the synthesis of the final product was investigated. The complex was characterized by elemental analyses, IR and UV-VIS spectroscopy, single crystal X-Ray diffraction and thermogravimetric analyses. The complex crystallizes in the monoclinic space group P2
1/c. The crystal structure reveals a homoleptic complex with a distorted octahedral geometry, where the ligand acts as monodeprotonated N, O-chelating anion.
