Abstract

Abstract : An unprecedented hybrid octamolybdate-based compound with both chiral and helical structure, consisting of a pair of enantiomorphous chiral "pinwheel" subunits, has been synthesized and its photocatalytic properties have been investigated. Abstract : A new polyoxometalate-based hybrid compound, [Cu(bimb)2 ]2 [β-Mo8 O26 ] (1 ) (bimb = 1, 3-bis(1-imidazoly)benzene), has been synthesized and characterized by single-crystal X-ray diffraction, IR spectrum, elemental analyses and powder X-ray diffraction. Structural analysis revealed that the structure of1 consists of a pair of chiral "pinwheel" subunits, and that such "pinwheel" subunits direct the formation of enantiomorphous chiral layers, in which the left- and right-handed helical chains are arranged regularly along the [001] direction. To the best of our knowledge, compound1 represents the first example of an octamolybdate-based compound with both chiral and helical structural features. In addition, a photocatalytic experiment indicated that the title compound presents good degradation activity and may be a potential photocatalyst to decompose the methylene blue dye.
