“…The electronic spectrum of NiL1 in chloroform exhibited bands at 590, 498, 424, 404 nm assigned to d-d and MLCT, respectively, while bands at 330 and 298 nm are assigned to the n-p* transitions of the azomethine nitrogens, and bands at 252 and 247 nm arise from phenyl p-p* transitions. Similarly, assigned bands were observed for NiL2 at 581, 491, 428, 404, 340, 320, 262 and 242 nm [16,17].…”

“…Peaks corresponding to the azomethine groups were observed for the ligand L. The observed syn-anti isomerism is associated with the double bond of the azomethine (HC=N 1 ) [17,25]. Syn-and antiisomers of L were defined by dual peaks with the 1:4 integral ratios.…”

“…Syn-and antiisomers of L were defined by dual peaks with the 1:4 integral ratios. Such cis-trans isomerism is common for such (C=N 2 ) [17,26,27]. The chemical shifts of the methyl protons of L are 2.48 and 2.45 ppm (cis/trans ratio 3:2).…”

“…The S-methylisothiosemicarbazone L exhibits strong bands at 1,612 and 1,582 cm -1 which correspond to the azomethine system (C=N 1 and N 2 ). An additional azomethine group (C=N 4 ) is observed after condensation of a second aldehyde to the thioamide nitrogen, positioned at 1,594 cm -1 for NiL1 and 1,597 cm -1 for NiL2 [17].…”

“…A number of studies on the synthesis and characterization of these compounds have been published [14,15]. Many metal-templated compounds synthesized from S-alkyl to thiosemicarbazones with various carbonyl compounds have been studied [16][17][18]. However, to date, the microbial activities of 3,5-di-tertbutylsalicylaldehyde-S-methylthiosemicarbazones have not been reported in the literature.…”

Ni(II) complexes were prepared by the reactions of 3,5-di-tert-butylsalicylaldehyde-S-methylisothiosemicarbazone (L) with salicylaldehyde or 2-hydroxy-1-naphthaldehyde in the presence of NiCl 2 Á6H 2 O. The complexes and starting material L were characterized by physicchemical analysis and spectroscopic techniques such as 1 HNMR, 13 CNMR, IR and UV-VIS. Antimicrobial activity studies of L and the two complexes standards strains of bacteria (Staphylococcus aureus, methicillin-resistant Staphylococcus aureus (MRSA), Bacillus cereus, Enterococcus faecalis, Streptococcus pneumoniae, Listeria monocytogenes, Escherichia coli, Salmonella typhi and Candida albicans) and 22 clinically isolated microorganisms, including multidrug resistant pathogenic microorganisms, were carried out. The free thiosemicarbazone L showed a significant inhibition of the growth all of Gram-positive bacteria tested.

2-Hydroxybenzaldehyde-4-allyl-S-methylisothiosemicarbazone and Cu (II), Co (III), Fe (III) and Cr (III) complexes were synthesized and characterized. The new obtained compounds were investigated by elemental analysis, magnetic susceptibility measurements, molar electric conductivity, IR, 1 H NMR, 13 C NMR, UV-Vis spectroscopy. In addition, the structure of the ligand and six complexes has been determined by single-crystal X-ray diffraction analysis.The Cu atom in complex 3 is penta-coordinated in a distorted square-pyramidal coordination geometry, while the metals in complexes 5-9 are in a distorted octahedral environment. For all compounds the antimicrobial activity was studied on a series of standard strains, such as Staphylococcus aureus, Escherichia coli, Enterococcus faecalis, Salmonella abony and Candida albicans.The in vitro antiproliferative activity of the ligand and complexes was screened on human leukemia HL-60 cells, human cervical epithelial HeLa cells, human epithelial pancreatic adenocarcinoma BxPC-3 cells, human muscle rhabdomyosarcoma spindle and large multinucleated RD cells. The primary screening on a wider series of cancer cells showed that copper coordination compound 2 manifests high activity towards HeLa, BxPC-3 and RD cancer cells, which is three-six times higher than the activity of doxorubicin. The selectivity index that is the ratio between the IC 50 value for the normal MDCK cells and IC 50 values for the cancer cells varies in the range 2.44-21.17. This index is 5.5-11 times higher for the copper coordination compound 2 than for the doxorubicin. Cr (III), Fe (III) and Co (III) coordination compounds 6-9 manifest high antioxidant activity towards ABTS •+ that exceeds 47-67 times the activity of Trolox. ---This is an open access article under the terms of the Creative Commons Attribution-NonCommercial License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited and is not used for commercial purposes.

New zinc (II), copper (II), nickel (II) and cobalt (III) complexes, [Zn (HL)2]I2 (1), [Cu (HL)Cl2] (2), [Cu (HL)Br2] (3), [Cu (HL)(H2O)2](ClO4)2 (4), [Ni (HL)2]I2·H2O (5), [Co(L)2]Cl (6), [Co(L)2]NO3 (7), [Co(L)2]I·[Co(L)2](I3) (8) were obtained with 2‐formylpyridine 4‐allyl‐S‐methylisothiosemicarbazone (HL). The isothiosemicarbazone ligand was characterized by NMR (1H and 13C), IR spectroscopy and X‐ray diffraction. All the complexes were characterized by elemental analysis, IR, UV–Vis, ESI‐MS spectroscopy, molar conductivity, magnetic susceptibility measurements. X‐ray diffraction analysis on the monocrystal and powder elucidated the structure of the complexes 1, 5, 7 and 8. The ligand and the complexes were tested for their antioxidant and antimicrobial activity against Staphylococcus aureus, Escherichia coli, Klebsiella pneumoniae and Candida albicans. Also, the antiproliferative properties of these compounds on human leukemia HL‐60, human cervical epithelial HeLa, human epithelial pancreatic adenocarcinoma BxPC‐3, human muscle rhabdomyosarcoma spindle, large multinucleated RD cells and normal MDCK cells have been investigated. The nickel complex 5 and cobalt complexes 6, 7 showed promising antiproliferative activity and low toxicity.
