A study on heterobimetallic chemistry of polyfunctional bis(2-hydroxy-1-naphthaldehyde) malonoyldihydrazone: Dioxouranium(VI),dioxomolybdenum(VI), zinc(II), copper(II), nickel(II) and cobalt(II) complexes

516-526The monometallic uranium(VI) complex [UO2(CH2LH2)(H2O)] has been synthesized from bis(2-hydroxy-1-naphthaldehyde) malonolydihydrazone (CH2LH4) in ethanol. The reaction of this complex with bis (acetylacetonato) dioxomolybdenum(VI) and metal acetates (M = Zn, Cu, Ni , Co and Mn) in 1:1 molar ratio in ethanol (methanol in the case of copper) under reflux yields hetcrobimetallic complexes [MUO2(CH2L)(H2O)2] (M = Zn and Cu) and [MUO2 (CH2L)(H2O)3] (M = MoO2, Ni, Co and Mn), respectively. The complexes have been<span style="font-size:12.0pt;font-family:HiddenHorzOCR; mso-hansi-font-family:" times="" new="" roman";mso-bidi-font-family:hiddenhorzocr"=""> characterized by analytical , molecular weight, molar conductance, magnetic moment data and spectral studies. In all the complexes, the dihydrazone coordinates to the metal centers in an anti-cis-configuration.
