Abstract

A novel 3D open-framework copper borovanadate with a unique crown-shaped anion [(V^IVO)₈(V^VO)₄B₃₂O₆₄(OH)₈]¹²⁻ and the largest ratio of Cu²⁺/borovanadate anions (6/1) has been successfully synthesized and systematically studied. The compound not only possesses high stability in a wide pH range of 3.2–10.8 (DMF solution), but also exhibits excellent catalytic activities for selective oxidation of sulfides.
