tow new compound of type [(chelate)2cu-oh-cu(chelate)2] x3.nh2o, where chelate=1,10-phenanthroline; x=cl¯(n=3.5) and chelate=4,4'-dimethyl-2,2'-bipyridine;  (n=5) have been synthesized and their properties investigated. the complexes show room temperature magnetic moment order of 1.0 b.m. per copper atom. the x-band esr spectrum of powdered samples at room temperature shows typical dm=1 transit...

Antianemic medicament ferrous gluconate, ferrous fumarate, and a Dynabi tablet with a basic iron bearing ingredient were studied with the use of Mössbauer spectroscopy. Room temperature spectra of ferrous gluconate gave clear evidence that the two phases of iron were present: ferrous (Fe2+) as a major one with a contribution at and above 91 a.u.% and ferric (Fe3+) whose contribution was found t...

background: ferrous sulfate is the most used supplement for treating anemia, but it can result in unfavorable side effects. nowadays, nanotechnology is used as a way to increase bioavailability and decrease the side effects of drugs and nutrients. this study investigates the effects of nanoparticles containing iron on blood and inflammatory markers in comparison to ferrous sulfate in anemic rat...

copper complexes of [cu(phen)(tda)].2h2o(1) and [(phen)2cu(µ-tda) cu(phen)](clo4)2.1.5h2o (2) (where phen is 1,10-phenanthroline and tda2- is thiodiacetate) have been synthesized. both complexes were characterized by elemental analysis, ir, uv–vis spectroscopy and cyclic voltammetry. their solid state structures were determined by the single crystal x-ray diffraction method. complex 1 is mononu...

Two polypyridyl copper(II) complexes, [Cu(phen)(phen-dione)Cl]Cl (1) and [Cu(bpy) (phen-dione)Cl]Cl (2), (where Phen =1,10-phenanthroline, bpy =2,2'-bipyridine and Phen-dione = 1,10-phenanthroline-5,6-dione), were used as efficient catalysts for the oxidation of benzyl alcohol to benzaldehyde. The effects of various parameters such as reaction temperature, reaction time, etc. were studied. The ...

In an effort to find practical means of distinguishing iron deficiency anemias from other types in large population groups, an investigation was made of the possibility of measuring iron in an amount of blood serum obtainable from the finger. Iron deficiency anemias are characterized by low serum iron, while other states of diminished hemoglobin formaCon show normal or even high values for seru...

The Oxford Whole Body Counter was used to measure absorption from various therapeutic preparations of iron in five groups of subjects. Succinic acid enhanced absorption of iron when added to a solution of ferrous fumarate, but not when given with tablets of ferrous fumarate or ferrous sulphate. Ferrous fumarate plus ascorbic acid was absorbed better than ferrous fumarate alone but no better tha...

Abstract Phenanthroline ligands bearing two biphenyl ( L1 ) or tetraarylbenzene L2 substituents have been synthetized and used to prepare bis‐phenanthroline copper(I) complexes. Steric constraints are limited in the case of biphenyl‐substituted ligand [Cu( 2 ](BF 4 has obtained by reaction with [Cu(CH 3 CN) ). In contrast, large enough totally prevent formation corresponding homoleptic complex....
