The new compound based on unconventional arsenomolybdate: {Co(btb)(H2O)(2))(2){H(2)As(2)M0(6)O(26)}center dot 2H(2)O (btb = 1,4-bis(1,2,4-triazol-1-y1)butane) (1) has been hydrothermally synthesized and characterized by single-crystal X-ray diffraction analysis, elemental analyses, IR, XPS, UV-vis-NIR and TG. Compound 1 consists of [H2As2MO6O26](4-) polyoxoanion and {Co-btb} complexes, the polyoxoanion as a tetradentate node coordinated with the Co2+ ions forming the rhombic 2D interpenetrated layer structure, which is further extended the 3D topological structure with symbol {4(6) . 6(2). 8(16) . 12(4))(4(9) . 6(6))(2){4}(2) by weak interaction. It shows obvious photo catalytic activities for the degradation of methylene blue (MB) and rhodamine-B (RhB). In addition, the electrocatalytic activity upon the reduction of nitrite also has been studied.
