Abstract

Abstract : A series of new organic–inorganic hybrid compounds based on Mo–V clusters and several types of transition metal complexes have been synthesized and characterized. Abstract : Three new compounds based on polyoxometalates and transition metal complexes have been prepared and characterized by IR and UV-vis spectroscopy, powder XRD, photoluminescence analysis, elemental analysis and X-ray diffraction analysis. Single crystal X-ray analysis reveals that both {[PMo10 V4 O42 ][Cu(phen)]2 }[Cu(im)2 ][Cu(phen)(im)]2 (1 ) (im = imidazole, phen = 1, 10-phenanthroline) and {[PMo9 V5 O42 ][Cu2 (2, 2′-bpy)2 (C2 O4 )]}[Cu(2, 2′-bpy)2 (H2 O)][Cu(2, 2′-bpy)2 (Cl)]·3H2 O (2 ) (bpy = bipyridine) contain three types of copper complexes, any one of which is different from the others. {[PMo8 V6 O42 ][Cu(DABCO)]2 [Cu(phen)2 ]}·3H2 O (3 ) (DABCO = triethylenediamine) exhibits a novel 2-D layered framework structure constructed from [PMo8 V6 O42 ] 4− and two different types of copper complexes, and also compound3 is the first extended POM compound based on {M(phen)2 } bridges. In addition, the catalytic properties of compounds1–3 have been investigated and all of them are excellent catalysts for the epoxidation of styrene.
