Mono and trinuclear complexes of alpha-oximinoacetoacetylpyridine-4-phenylthiosemicarbazone.
Complexes of several transition metal ions with alpha-oximinoacetoacetyl pyridine-4-phenylthiosemicarbazone (H3OAPT) have been prepared. Attempts were made to elucidate their geometries by elemental analysis, molar conductance, magnetic measurements and by some spectroscopic (IR, ESR and electronic) techniques. All the investigated metal ions form mononuclear complexes except for CuII, which fo...

Are social movements responsible for their unfi nished agendas? Feminist successes in opening the professions to women paved the way for the emergence of the upper middle-class two-career household. These households sometimes hire domestic servants to accomplish their child care work. If, as I shall argue, this practice is unjust and furthers social inequality, then it poses a moral problem for...
متن کاملSimultaneolls spectrophotometric determination of molybdenum ( VI ) and titanium ( IV ) using 2 , 4 - dihydroxybenzaldehyde isonicotinoyl hydrazone
Determination of molybdenum(VI) by direct spectrophotometry and simultaneous determination of molybdenum(VI) and titanium(IV) are reported. Molybdenum(VI) gives a golden yellow colour with 2,4dihydroxybenzaldehyde isonicotinoyl hydrazone with a 1:2 metal-reagent stoichiometry at pH 1.5. The complex shows an absorption maximum at 445 nm with molar absorptivity and Sandell's sensitivity of 1.02x1...
متن کاملNovel binuclear copper(II) complexes of di-2-pyridyl ketone N(4)-methyl, N(4)-phenylthiosemicarbazone: Structural and spectral investigations
Four binuclear complexes [Cu(dptsc)Cl]2 Æ 3H2O (1), [Cu(dptsc)Br]2 (2), [Cu(dptsc)(l-N3)]2 (3) and [Cu(dptsc)(NO3)]2 Æ H2O (4) (where Hdptsc = di-2-pyridyl ketone N(4)-methyl, N(4)-phenylthiosemicarbazone) have been synthesized and physicochemically characterized. Each Cu(II) atom in the monomeric unit exists in a penta-coordinate environment. The molecular structures of [Cu(dptsc)Br]2 and [Cu(...
