摘要
A (PMO12O40}-directed organic-inorganic hybrid compound H3O[Mo-6(bpy)(6)O-17][PMo12O40].2H(2)O (1) (bPY = 2,2'-bipyridine) has been hydrothermally synthesized and characterized by the elemental analysis, IR, XRD, TG analysis and single-crystal X-ray diffraction. In compound 1, Keggin heteropolyanions as templates induce the [MoO4(bpy)] complexes to form unusual wave-liked hexa-molybdenum unit's chains, which are further linked to form pure Mo-oxide-based host layers via supramolecular interaction. {PMo12) as guest units is grafted on the host layer to result in Keggin ions layers. The host cation layers and Keggin ions layers alternately array together to form unique sandwich-type supramolecular networks. In addition, the solid state fluorescent properties, and electro- and photo-catalytic behaviors of compound 1 have been studied.
