Аннотация

Self-assembly reactions in the Na₂MoO₄/SeO₂/H₂C₂O₄system lead to the formation of a tubular [(SeMo₆O₂₁)₂(C₂O₄)₃]¹⁰⁻hybrid polyanion, isolated and characterized by single crystal X-ray diffraction (SCXRD) as Na₉H[(SeMo₆O₂₁)₂(C₂O₄)₃]·NaNO₃·20.6H₂O (SeMo6-1). Dehydration of this compound leads to the formation of Na₁₀[(SeMo₆O₂₁)₂(C₂O₄)₃]·0.5NaNO₃·8H₂O (SeMo6-2). The electrochemical behavior ofSeMo6-2as a component of the paste electrode was studied by CV in CH₃CN solution. A concentrated aqueous solution ofSeMo6-2was studied using⁷⁷Se and⁹⁵Mo NMR techniques, which show extensive degradation of the complex. Addition of TBABr to the concentrated solution leads to a precipitate consisting of TBA salts of [Mo₆O₁₉]²⁻and [β-Mo₈O₂₆Na₂(NO₃)₂]²⁻anions. The latter was characterized by SCXRD as (TBA)₃[β-Mo₈O₂₆Na₂(NO₃)]·CH₃CN (Mo8-Na). This transformation shows the presence of [β-Mo₈O₂₆]⁴⁻and [Mo₆O₁₉]²⁻in the aqueous solution ofSeMo6-2. The study of (NBu₄)₄[β-Mo₈O₂₆] and (NBu₄)₂[Mo₆O₁₉] solutions in CH₃CN by HPLC shows equilibration between [β-Mo₈O₂₆]⁴⁻and [Mo₆O₁₉]²⁻
