dc.description.abstractThe flexibly-bridged tetraanionic hexadentate ligands (LH4), methylenbis(salicylaldehyde-o-hydroxybenzylamine) [CH2(H2sal-OHYBA)2] and methylenebis(salicylaldehyde –o-aminobenzylalcohol) [CH2(H2sal-OABA)2] react with acetates of copper(II), nickel(II), cobalt(II), dioxouranium(VI) to give the corresponding metal complexes of formula [Cu2L], [Ni2L.4H2O), [Co2L.4H2O] and [(UO2)2L.2CH3OH], respectively. Reaction of these ligands with [MO2(acac)2](M=Mo, W) in refluxing methanol affords [(MO2)2L.nCH3OH] (n=0 or 2). Thermogravimetric analyses confirm the coordination of H2O/CH3OH in complexes.1H NMR spectral data of molybdenum, tungsten and uranium complexes suggest coordination of the ligands through deprotonated phenolic/enolic oxygen and azomethine nitrogen atoms. Electronic spectral data suggest square planar structure for copper complexes while an octahedral structure for other complexes.en_US
