Abstract

Two decavanadates (trisH)₄[H₂V₁₀O₂₈]·10H₂O (1) and (trisH)₆[V₁₀O₂₈] (2) have been synthesised from NaVO₃ or V₂O₅ in an aqueous solution of tris(hydroxymethyl)aminomethane (tris). Bimetallic derivatives [Cu(OH₂)₅(trisH)]₂[V₁₀O₂₈]·6H₂O (3) and [Cu(OH₂)₃(2–amp)]₂(trisH)₂ [V₁₀O₂₈]·2H₂O (4) were obtained by the addition of CuCl₂ or CuCl₂ / 2–amp (2–(aminomethyl)pyridine) to the route that gave 2. The products were characterised by single-crystal X-ray diffractometry, thermogravimetric analysis, FTIR, Raman and EPR spectroscopies. Moreover, 4 was effective in bleaching a methylene blue (MB) solution under natural light in acidic media by either degradation of the dye or precipitation of a MB-decavanadate salt depending on the experimental conditions.
