Formation Mechanism of a Nano-Ring of Bismuth Cations and Mono-Lacunary Keggin-Type Phosphomolybdate.

ABSTRACT: A new hetero-bimetallic polyoxometalate (POM) nano-ring was synthesized in a one-pot procedure. The structure consists of tetrameric units containing four bismuth-substituted monolacunary Keggin anions including distorted [BiO₈ ] cubes. The nano-ring is formed via self-assembly from metal precursors in aqueous acidic medium. The compound (NH₄ )₁₆ [(BiPMo₁₁ O₃₉ )₄ ] ⋅ 22 H₂ O; (P₄ Bi₄ Mo₄₄ ) was characterized by single-crystal X-ray diffraction, extended X-ray absorption fine structure spectroscopy (EXAFS), Raman spectroscopy, matrix-assisted laser desorption/ionisation-time of flight mass spectrometry (MALDI-TOF), and thermogravimetry/differential scanning calorimetry mass spectrom
