Graphical Abstract: A new Co(III) complex [CoIII(2,3-pdcH)3(H2O)3] (2,3-pdcH – monoanion of 2,3-pyridinedicarboxylic acid) has been synthesized from Co(II) salt at room temperature by using nonhydrothermal method and (NH4)2S2O8 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 P21/c. The crystal structure reveals a homoleptic complex with a distorted octahedral geometry, where the ligand acts as monodeprotonated N, O-chelating anion.
