摘要: Two new belt-like borates Na4[B9O14(OH)3]·0.5H2O(1) and Na5[B9O14(OH)4](2) have been synthesized under solvothermal conditions. Both compounds contain unprecedented B9O16(OH)n(n+5)-[n=3(1), 4(2)] clusters, which are constructed from four B3O3 rings via three BO4 tetrahedra. Compound 1 exhibits a rare 1D belt with two types of 8-membered ring(MR) windows based on B9O16(OH)38- clusters. Compound 2 features two different 1D belts built by different B9O16(OH)49- 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.
