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

•A new arsenomolybdate has been synthetized with unprecedented fragment.•Compound 1 displays better electrocatalytic activity on the reduction of nitrite.•Compound 1 has better photocatalysis on MB.

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.
