A terdentate ligand (Ambtn) was obtained by condensing 2-aminobenzaldehyde with 1,3-diaminopropane which reacts with MoO₂ (acac)₂ in methanol medium to form a series of mononuclear oxomolybdenum(VI), dinuclear molybdenum(V) and mononuclear molybdenum(IV)  complexes. These oxomolybdenum(VI) and molybdenum(V) complexes are diamagnetic, whereas oxomolybdenum(IV) complex is paramagnetic, all these complexes are non-electrolyte and the complexes contain MoO²⁺, Mo₂O₃⁴⁺ and MoO²⁺ species respectively. These complexes are characterized on the   basis  of  elemental analysis, IR,    UV-Visible, ESR spectras, conductivity, magnetic measurements and cyclic voltammogram studies.
