A new low-nuclear polymolybdate cluster [Cu_4~Ⅱ(opr)_2(Mo_(12)O_(40))]_n·2n H_2 O was successfully isolated by the introduction of flexible multidentate 1,1?-(1,3-propanediyl)bis[2-(2-pyridyl)benzimidazole ligand(opr),(NH_4)_6Mo_7O_(24)·4H_2O,and copper(Ⅱ) ions under hydrothermal conditions. Single-crystal X-ray analysis reveals that the complex crystallizes in the P2_1/n space group with a = 13.8437(5),b =19.3953(6),c =15.7681(6) ?,β =112.698(4)o,V = 3905.9(2) ?~3,Z = 4,D_c = 2.502 g/cm~3,μ = 3.020 mm~(-1),F(000) = 2824,the final R = 0.0352,wR = 0.0523 and S = 0.783 for 7111 observed reflections with I > 2σ(I). The structure of the compound contains a new type of low-nuclear(Mo_(12)O_(40))~(8-)polymolybdate cluster. These dodecamolybdate anions are linked together through sharing edges to form a 1D molybdenum oxide chain. Its photocatalytic performance for methylene blue(MB) was also studied under UV irradiation.
