摘要
Two new borates Na2Ba[B5O8(OH)]2·2H2O(1) and KSr[B5O8(OH)2](2), with deep UV cutoff edges, were solvothermally made by using mixed alkali and alkaline-earth metal templates. They were further characterized by single-crystal XRD, powder XRD, IR spectra, UV-Vis absorption spectra and thermogravimetric analysis. Compound 1 crystalizes in the monoclinic space group P2/c. 4-connected B5O10(OH) cluster build 2D monolayer with two kinds of 9-MR windows via corner-sharing. Compound 2 crystalizes in the monoclinic space group C2/c. 4-connected B5O10(OH)2 cluster construct 2D fluctuant layer with different 8- and 12-MR unclosed channels along two different directions. Both 1 and 2 exhibit the cutoff edge below 200 nm, indicating their potential applications in UV and deep UV regions.
