“…The N(3)H and (O-H) resonances are observed at 11.77 and 12.40 ppm, respectively, and these two singlets were absent when using DMSO-d 6 /D 2 O as a solvent. Similar 1 H NMR data have been reported for the diacetylmonoxime Schiff base of S-benzyldithiocarbazate [5]. The syntheses of the metal complexes employed 1:1 or 1:2 metal/ligand molar ratios, and the analytical data of the complexes are in a good agreement with their proposed formulae.…”

“…In particular, the angles S3-Fe-N12 [161.72 (10) (14)°] are less than the ideal value of 180°. It is likely that these contractions originate in the relatively restricted bite size of each of the chelating groups, as similarly found for bis-NNS tridentate ligands of metal(III) and metal(II) complexes [5,20,21]. The two monoanionic ligands (Hdamsm -) are coordinated in the meridional configuration, such that the two thiol sulfur atoms S2 and S3 and the two oxime nitrogen atoms N7 and N12 are cis to each other, while the imine nitrogen atoms N10 and N8 are trans to each other.…”

“…Less attention, however, has been paid to Schiff bases obtained from the condensation of S-methyl-or S-benzyl dithiocarbazate with diacetylmonoxime [5,6]. There is interest in the coordination chemistry of oximes as they have served as models for biological systems such as vitamin B12 and as myocardial perfusion imaging agents [7].…”

The complexes [M(Hdamsm) 2 ]XÁH 2 O (M = Fe, X = NO 3 ; M = Ru, X = Cl), [Ru(Hdamsm)(PPh 3 ) 2 X 0 ] (X 0 = Cl, Br), and [VO(Hdamsm)(acac)] (H 2 damsm = diacetylmonoxime Schiff base of S-methyldithiocarbazate, Hacac = acetylacetone) have been prepared and characterized by spectroscopic techniques. Their redox properties were investigated by cyclic voltammetry. The X-ray crystal structure of [Fe(Hdamsm) 2 ]NO 3 .H 2 O has been determined and shows that the complex has a distorted octahedral geometry in which the Hdamsm behaves as a monoanionic NNS tridentate ligand coordinating via oxime nitrogen, hydrazinic imine nitrogen, and thiolate sulfur. The reactivity of these complexes toward oxidation of alcohols in the presence of t-BuOOH and H 2 O 2 as co-oxidants is reported.

“…And, the strong absorption at 404 nm is due to LMCT transition. The electronic spectra of the other complexes are of little help in the present case at the visible region, since the d→d transitions are masked by the strong charge-transfer transition bands [33]. 505, 438 and 433 nm absorptions for the Fe(II), Ni(II) and Co(II) complexes, respectively, can be accepted CT transitions.…”

ABSTRACT. Cr(III), Fe(II), Fe(III), Co(II), Ni(II), Cu(II), Zn(II) complexes of N-(5-chloro-2-hydroxyphenyl)-3-methoxy-salicylaldimine (H2L), an ONO type tridentate ligand, were synthesized and characterized by elemental analysis, magnetic moment, molar conductivity, TGA, NMR, IR, UV-vis. and ESI-MS spectral techniques. All of the complexes except [Zn(L)(H2O)2] are paramagnetic. The CoCl2 gives a complex with 1:2 M:L ratio while the others form 1:1 non-ionic complexes with H2L. The ligand coordinated to the metal ions through the both OH oxygen and the azomethine nitrogen atoms acting tridentate behaviour. Octahedral geometry has been proposed for the Fe(II), Cr(III), Co(II), Ni(II) complexes considering the magnetic moment values and the electronic spectral data. The Zn(II) and Fe(III) complexes exhibit five coordination geometries and the Cu(II) complex is four-coordinated having acetato bridged dimeric structure. Antimicrobial activities of the compounds were determined against six bacteria and C. albicans as fungi. The Ni(II) and Co(II) complexes exhibit considerable selective activity on S. epidermidis and C. albicans whereas the ligand has no activity on the microorganisms. In addition, the Cr(III) complex shows antibacterial activity toward S. epidermidis and the Zn(II) complex has antifungal activity on C. albicans.

“…However, these compounds are applied at complexometric process and the various complexes synthesis. Some factors that lead to value oximes characteristic, is these material application at other material synthesis [6][7][8][9][10][11][12][13][14][15][16] . These compounds are used to identify aldehydes and ketenes.…”

ABSTRACT2-(piperidine-1-ylmethyl)cyclohexanone (PMC), 2-(piperidine-1-ylmethyl)cyclohexanone oxime (PMCO) structures and also 2-(piperidine-1-ylmethyl) cyclohexan amine (PMCA) structure were extracted using experimental methods of Mannich reaction, based on oxime protected compounds. The given structures were purified at the end of syntheses process, by chromatography column. Related structures were identified by using 13 C-NMR, 1 H-NMR, FT-IR and mass spectroscopy. Attained results showed that using oxime structure as an intermediate causes to increase the yield and also to increase reaction ratio attain final product. However, all the attained spectra approved existence of intermediate and the final product. In following, thermodynamic parameters for the products including energetic levels, HOMO and LUMO parameters, chemical hardness, electrophilicity and chemical potential for this structures were calculated by using the density functional theory in method and B3LYP/6-311G(d,p) level of theory.
