Interaction of arsenite ions with molybdate ions in aqueous HClO4 at pH of 3–5 were studied using
spectrophotometry. A heteropoly anion (HPA) with the AsMo4 stoichiometry was revealed. Elemental analysis,
X-ray photoelectron spectroscopy, and IR spectroscopy were used to characterize the composition and structure
of the cesium salt of As(III)–Mo(VI) HPA precipitated from solution. The comparison of the IR spectra of
cesium salts of the synthesized HPA and dimethylarsenite HPA (CH3)2AsMo4O15H2–, whose structure is
known, implies that AsMo4 has a similar structure, where the As group is linked by four connected
molybdenum octahedra (Mo4O12)O2–.
