in present studies the synthesis, characterization and biological properties ofoxovanadium(iv) coordination compounds of 4[n-(4′-ethylbenzalidene)amino] antipyrinethiosemicarbazone (ebaapts) and 4[n-(2′,4′-dimethylbenzalidene)amino] antipyrinethiosemicarbazone (dmbaapts) with the general composition vox2l (x = c1-, br-, i-, no3-or ncs-) and vo(cio4)2(l)h2o (l = ebaapts or dmbaapts) are describe...

the vo(iv) complexes of tridentate ono schiff base ligands derived from 2- aminobenzoicacid and salicylaldehyde derivatives were synthesized and characterized by ir, uv–vis and elemental analysis. electrochemical properties of the vanadyl complexes were investigated by cyclic voltammetry. a good linear correlation was observed between the oxidation potentials and the electron-withdrawing charac...

few novel cobalt(ii) and copper(ii) complexes [m(fmp)3]cl2, [m(fmp)(bpy)2]cl2,[m(fmp)(phen)2]cl2 and [m(fmp)(phen)(bpy)]cl2 (fmp = 3-furan-2-ylmethylene-pentane-2,4-dione, phen = 1,10-phenanthroline, bpy = 2,2'-bipyridine) have been synthesized andcharacterized by elemental analyses, molar conductance, magnetic susceptibility measurements,ir, electronic, epr, mass spectra and cyclic voltam...

glipizide has been found to form inclusion complexes with β-cyclodextrin (β-cd) in solution and in solid state. the present study was undertaken to determine a suitable method for scaling up glipizide-β-cd inclusion complex formation and to evaluate the effect of some parameters on the efficiency of complexation. the solid inclusion complexes of glipizide and β-cd were prepared at a molar ratio...

during the islamic period of iran except for public complexes including buildings as bazaar, reservoir, caravansary, etc. there were burial complexes that occupy a special place in the architecture of the epoch. these complexes were first built as the burial ground of a famous political or religious figure and along the time other buildings such as mosque, madreseh (school), monastery, caravans...

New hetero-binuclear Hg-Cu Schiff base complexes were prepared by reaction of 2,2'-[1,1'-(2,2-‎dimethylpropane-1,3-diyldinitrilo)-diethyldyne]diphenolato}copper(II) (CuL1) and 6,6'-X-2,2'-[(2,2-‎dimethylpropane-1,3-diyl)bis(nitrilomethanylylidene)]diphenolato copper(II) [(X = ethoxy (CuL2) and ‎methoxy (CuL3)], with HgCl2 to give [Cu(L1)HgCl2] (1), [Cu(L2)HgCl2] (2), and [Cu(L3)HgCl2] (3), ‎res...

AbstractThe ability of hesperidin (HP) to form complexes with five metals; cobalt, nickel, zinc, calcium and magnesium was investigated. The complexation was studied using U.V spectroscopic titration, in methanol as well as aqueous buffer solutions (physiological conditions). Potential complexes were studied by IR and NMR spectroscopy, melting point and their solubility were also evaluated. The...
