Abstract: The alkali metal and ammonium oxodiperoxomolybdenum(VI) complexes M[MoO(O2)2 (Hsih)]. H2O {M = K(1), Na(2),and NH4(3)} and dioxoperoxomolybdenum(VI) complexes M[MoO2(O2)(Hsih) (C2H5OH)].H2O {M = K(4) and Na (5)} derived from salicylaldehyde isonicotinoylhydrazone (H2sih) have been synthesized in aqueous-ethanol media. The structural assignment of the complexes has been carried out on the basis of molar conductance, magnetic moment, EPR data and IR spectroscopic studies. H2sih coordinates to the metal centre in keto form as a monobasic bidentate ligand through phenolate oxygen atom and azomethine nitrogen atom. Peroxide is coordinated to the metal centre in a bidentate chelating fashion. All the complexes are proposed to have seven coordinate polyhedra around the molybdenum centre.
