Two novel asymmetrical Schiff-base ligands, H2L1 and H2L2, were prepared by reacting two half-unit Schiff-base compounds with 2-methyl-7-formyl-8-hydroxyquinoline. The two half-unit Schiff-base compounds were initially prepared by condensing dimedone

Two novel symmetrical Schiff base ligands, H2L1 and H2L2, with tetradentate N2O2 and pentadentate N3O2 coordinating sites were prepared by the reaction of the aldehyde 2-methyl-7-formyl-8-hydroxy-quinoline with 1,3-diaminopropane or diethylenetriamin

Monosulfito and bis(hydrogensulfito) cobalt(III) complexes were prepared using sodium sulfite and sodium metabisulfite salts respectively. The two types of products showed different and characterizing patterns of IR and UV-visible spectra. They both

The effect of solvent structure on the rates of redox reactions in alcohol+water mixture was discussed by some authors. The rate of photoreduction of 9,10-anthraquinone-2-sulfonate was decreased by addition of H2SO4 but was unchanged by increase of i

Normal sulphites of metals were prepared by the reaction of metal salts with sodium metabisulphite, in aqueous acid solutions, to prevent the formation of basic sulphites. Visible spectra and magnetic moments show that the transition metal sulphites
