英文摘要：

A new octamolybdate based organic-inorganic hybrid compound,namely [Ni2（ptz H）3（H2O）6]（β-Mo8O（26））·2H2O（ptz H=5-（3-pyridyl）-1H-tetrazole）, was hydrothermally synthesized by using the ptz H ligand and characterized by single-crystal X-ray diffraction, elemental analyses and IR spectrum. There exist two discrete subunitsin title compound： the β-type octamolybdate cluster [Mo8O（26）]-（4-） and the cationic dimer [Ni2（ptz H）3（H2O）6]-（4＋）. In the dimer, two Ni ions are fused by three ptz H molecules. There are abundant π …π stacking interactions between these Ni dimers and a supramolecular metal-organic layer is constructed with rhombus grids. The [（β-Mo8O（26））]-（4-） anions embed in these rhombus grids by offering plenty hydrogen bonding interactions. The electrochemical and photocatalytic properties of the title compound have been studied.
