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.

Abstract (PDF)
Graphical Abstract: A new synthetic extractive protocol for the synthesis of Cu(II) and Co(III) complexes of bis(2,2/-methylylidenephenol)diaminoethane (H2BMPDE) in a single simple step was performed. The obtained data indicated the formation of complexes with 1:1 molar ratio of metal:ligand, of distorted square planar and distorted octahedral geometries. In vitro antibacterial screening revealed that the complexes were active against clinically important gram-negative bacteria (Escherichia coli, pseudomonas, and gram-positive bacterium (Staphylococcus aureus). The synthesis of the complexes was optimized to make it more suitable and efficient for industrial scale production.
