The synthesis, structure and properties of a new compound with 1D linear chain arsenomolybdate anion building block

The new inorganic-organic hybrid arsenomolybdate {Cu(2,2'-bPY)}(2){H2As2MO2O14} (2,2'-bPy = 2,2'-bipyridine) (1) has been hydrothermally synthesized and characterized by single-crystal X-ray diffraction analysis, elemental analyses, X-ray powder diffraction (XRPD), IR spectroscopy, UV spectroscopy, XPS spectroscopy and thermogravimetric analysis (TG). Compound 1 presents an infinite 1D chain structure based on the unprecedented H2As2MO2O14}(4-) fragment and transition-metal complex {Cu(2,2'-bpy)}(2+). Compound 1 displays obvious electrocatalytic activities toward the reduction of nitrite and better photocatalytic activities for the degradation of methylene blue. (C) 2015 Elsevier B.V.
