The bond length, bond angle, HOMO, LUMO, dipole moment and charges on the atoms have been calculated to confirm the geometry of (E1, E2) N1,N2 - bis[1-(3,4-dihydroxyphenyl)ethylidene]oxalohydrazide, H6DPOH. The metal complexes of Cr3+, VO2+, ZrO2+, HfO2+, UO2 2+ and MoO2 2+ with H6DPOH have been prepared and characterized by partial elemental analysis, spectral studies (electronic; IR), thermal analysis and magnetic measurements. The data suggest the formation of [Cr(H4DPOH)(H2O)3Cl]H2O, [VO(H4DPOH)(H2O)2], [Hf(H4DPOH)(H2O)]H2O [UO2(H4DPOH)(H2O)2]2H2O [MoO2(H4DPOH)] and [(ZrO)2(H2DPOH)(C2H5OH)2]. H6DPOH behaves as a dibasic bidentate in all complexes except ZrO2+ which acts as a tetrabasic tetradentate for the two ZrO2+ ions. An octahedral geometry was proposed for the Cr3+, HfO2+, MoO2 2+and UO2 2+ complexes and square pyramid for VO2+. The Cr(III) or VO2+ complexes are necessary to degrade the DNA of Eukaryotic subject completely; the other complexes have little effect. H6DPOH was found applicable as a new reagent for the separation and preconcentration of ZrO2+ ions from different water samples using flotation technique with satisfactory results.

Abstract


The bond length, bond angle, HOMO, LUMO, dipole moment and charges on the atoms have been calculated to confirm the geometry of (E1, E2) N1,N2 - bis[1-(3,4-dihydroxyphenyl)ethylidene]oxalohydrazide, H6DPOH. The metal complexes of Cr3+, VO2+, ZrO2+, HfO2+, UO2 2+ and MoO2 2+ with H6DPOH have been prepared and characterized by partial elemental analysis, spectral studies (electronic; IR), thermal analysis and magnetic measurements. The data suggest the formation of [Cr(H4DPOH)(H2O)3Cl]H2O, [VO(H4DPOH)(H2O)2], [Hf(H4DPOH)(H2O)]H2O [UO2(H4DPOH)(H2O)2]2H2O [MoO2(H4DPOH)] and [(ZrO)2(H2DPOH)(C2H5OH)2]. H6DPOH behaves as a dibasic bidentate in all complexes except ZrO2+ which acts as a tetrabasic tetradentate for the two ZrO2+ ions. An octahedral geometry was proposed for the Cr3+, HfO2+, MoO2 2+and UO2 2+ complexes and square pyramid for VO2+. The Cr(III) or VO2+ complexes are necessary to degrade the DNA of Eukaryotic subject completely; the other complexes have little effect. H6DPOH was found applicable as a new reagent for the separation and preconcentration of ZrO2+ ions from different water samples using flotation technique with satisfactory results.
