| Abstract: | The synthesis and structure of a new 1-D molybdenum-arsenic compound based on the bi-capped Keggin anion MoVI6MoV6O36(AsO4)(MoVO)2]− have been reported, and its catalytic property has been examined. The title compound was characterized by IR, TG and X-ray diffraction analysis. Single crystal X-ray diffraction shows that it crystallizes in cubic crystal system, space group Pn-3m with cell dimension: a = 11.749(2) Å, V = 1622.0(5) Å3, Z = 2. Its structure has a 1-D infinite chain, in which the bi-capped Keggin anions are connected by sharing one terminal oxygen atom from the caps. The compound shows a moderate styrene conversion (48%), the major product for the oxidation of styrene is benzaldehyde (85.2%). |
