Abstract

Abstract: The building‐block assembly of polyoxometalates to form crystalline MoV‐based metal oxides is presented. Mixing of (NH4 )6 Mo7 O24 and VOSO4 in water with a pH value higher than 1.7 produced the ball‐shaped polyoxometalate [Mo72 V30 O282 (H2 O)56 (SO4 )12 ] 36– ({Mo72 V30 }) with 12 pentagonal [Mo6 O21 ] 6– polyoxomolybdate units connected to 30 [V=O] 2+ units, which was detected by using UV/Vis, Raman, and IR spectroscopy. Hydrothermal reaction of the precursor containing {Mo72 V30 } produced crystalline orthorhombic or trigonal MoV oxides. These oxides contain the pentagonal Mo unit in the crystal structure. The results indicate that the pentagonal polyoxomolybdate unit produced in the reaction precursor assembles with other Mo and V ions to form crystalline orthorhombic and trigonal MoV oxides.
