Rezumat

A new Co(III) complex [Coⁱⁱⁱ(2,3-pdcH)3]·3H2O, (2,3-pdcH2 - 2,3-pyridinedicarboxylic acid) has been synthesized from a Co(II) salt at room temperature by using (NH4)2S2O8 as oxidant. The complex was characterized by elemental analysis, IR and UV-Vis spectroscopy, 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 a monodeprotonated N, O-chelating anion

Cuvinte-cheie
Co(III) complex, 2, 3-pyridinedicarboxylic acid, thermal analysis, X-ray diffraction.
