“…The mass spectra peaks of the other L 2 complexes [Cu 2 (L 2 )(OAc) 4 ]∙2H 2 O∙2DMF, [Cu(L 2 ) 2 ]∙2NO 3 ∙1.5DMF∙H 2 O, [Zn(L 2 ) 2 (NO 3 ) 2 ]∙DMF and [Zn 2 (L 2 )(OAc) 4 (H 2 O) 4 ]∙5H 2 O are attributable to the related molecular ions m/z : 807.21 [M+H] + , 838.14 [M+H] + , 785.32 [M+H] + and 545.20 [M-2OAc − -7H 2 O] 2+ , respectively. The observed free ligand L 1 peaks for all of the complexes are m / z : 247.11 [L+H] + [38,39]. The observed free ligand L 2 peaks for each two complexes are similarly m / z : 262.08 [L+H] + except for the [Zn(L 2 ) 2 (NO 3 ) 2 ]∙DMF complex.…”

Some new Zn(II) and Cu(II) complexes [Cu(LC-NMR and ultraviolet (UV-Vis.) spectroscopy, elemental analysis, magnetic susceptibility, mass spectrometry and thermogravimetrydifferential thermal analysis (TGA-DTA). The synthesized ligands and their complexes were tested for antibacterial activity against Escherichia coli ATCC 25922, Enterococcus faecalis ATCC 29212, Staphylococcus aureus ATCC 25923, and Salmonella typhimurium CCM 583. Some of complexes showed medium-level antibacterial activity against the test bacteria compared with ampicillin.

In this study, firstly, bis(thiosemicarbazone) ligand [L: 2,2′-(2-(2-(4-methoxyphenyl)hydrazineylidene)cyclohexane-1,3-diylidene)bis(hydrazine-1-carbothioamide)] was synthesized by the condensation reaction of thiosemicarbazide and ketone compound (2-(2-(4-methoxyphenyl)hydrazone)cyclohexane-1,3-dione). The metal complexes were synthesized by the reaction of obtained ligand (L) with CuCl2·2H2O, NiCl2·6H2O, CoCl2·6H2O, and MnCl2·4H2O salts. The structures of synthesized ligand and their complexes were characterized using elemental analysis, IR, UV–Vis, 1H-NMR spectra, 13C-NMR spectra, magnetic susceptibility, mass spectra (LC–MS), thermogravimetry analysis-differential thermal analysis (TGA-DTA), and differential scanning calorimetry techniques. According to the results of the analysis, square plane geometry was suggested for Cu and Co complexes. However, the structures of Ni and Mn complexes were in agreement with octahedral geometry. Molecular docking analysis and pharmacological potential of the compound were evaluated to determine the inhibitory potential against acetylcholinesterase (AChE) and Glutathione-S-transferases (GST) enzymes. The compound exhibited strong binding/docking indices of − 5.708 and − 5.928 kcal/mol for the respective receptors. In addition, L–Ni(II) complex was found to be the most effective inhibitor for AChE enzyme with a Ki value of 0.519. However, with a Ki value of 1.119, L–Cu(II) complex was also found to be an effective inhibitor for the GST enzyme.
