摘　　要：Two new belt-like borates Na_(4)[B_(9)O_(14)(OH)_(3)]·0.5H_(2)O(1)and Na_(5)[B_(9)O_(14)(OH)_(4)](2)have been synthesized under solvothermal conditions.Both compounds contain unprecedented B_(9)O_(16)(OH)_(n)^((n+5))−[n=3(1),4(2)]clusters,which are constructed from four B_(3)O_(3) rings via three BO_(4) tetrahedra.Compound 1 exhibits a rare 1D belt with two types of 8-membered ring(MR)windows based on B_(9)O_(16)(OH)_(3)^(8−) clusters.Compound 2 features two different 1D belts built by different B_(9)O_(16)(OH)_(4)^(9−) units,which is first discovered in borate family.UV-Vis diffuse reflectance spectra reveal that compounds 1 and 2 have the cut-off edges below 190 nm,indicating that they may have potential application in deep UV(DUV)region.
