the in-situ method of synthesis has been used to isolate oxovanadium(iv) complexes with ligands derived by reaction of benzil with amino acids such as glycine, alanine, serine, cysteine and valine, where template effect of vo +2 cation appears to play an important role. the complexes are characterised by elemental analysis, magnetic moment measurements and spectral (infrared, electronic and ele...

A series of new heteroleptic chelated copper(II) complexes that encompass N,N-dibezyl substituted derivative of ethylenediamine (X-diamine) and acetylacetonate (acac) were prepared.  The IR and electronic absorption spectra and the molar conductivity of the complexes are presented and discussed.  The molar conductivity values of the complexes in different solvents reveals a predominance of elec...

keeping in view the promising potential of carbonic anhydrase inhibitor based antimicrobials and enhancement of carbonic anhydrase inhibitory activity by metal complexes of sulfonamides, with an aim to develop better antimicrobial agents we have attempted investigation of antimicrobial activity of metal complexes of 4-(2'-hydroxy phenyl imino) phenyl sulphonamide. sulfanilamide was taken a...

Four new [NiH2L](ClO4)2 (1), [CuH2L](ClO4)2 (2), [MnH2L](ClO4)2 (3) and [CdH2L](ClO4)2 (4), complexes were prepared by the reaction of a new Schiff base ligand and Cu(II), Ni(II), Mn (II) and Zn (II) metal ions in equemolar ratios. The ligand, H2L was synthesized by reaction of 1, 4- bis (2- formylphenyl) piperazine and ethanol amine and characterized with IR and 1H,13C NMR spectroscopy. All co...

the role of cu, zn and co in human physiology is well documented. isatin and glycine have inhibitory effects on central nervous system. to capitalize on these features metal complexes of isatin-3-glycine were prepared and evaluated for anticonvulsant activity. the cu (ii) complex was found to be most active among the compounds. the compounds were screened against staphylococcus aureus, escheric...

Compounds composed of [Cu(HIm, metIm)2–3L] ∙ nH2O (n = 0, 2) were obtained during the interaction slightly soluble tartrate and copper(II) salicylate CuL 1–2, L2−—Tar2−, Sal2−) with imidazole (HIm) 2-methylimidazole (metIm). Mono- bi-ligand salts analyzed; process their thermal decomposition was studied. The solubility constants KS CuC4H4O6 2H2O CuC7H4O3 H2O at ionic strength 0.3 determined. IR...
