| Abstract: | A new layered beryllium polyborate H2BeB4O8 was synthesized in molten boric ac id flux. It crystallizes in the monoclinic space group P21/n with lattice consta nts a=17.75640(15)?, b=4.2948(1)?, c=7.1532(1)?, a=96.8797(9)-ray diffraction techniq ues, is composed of double three-membered ring unit [BeB4O11], which is further connected by corner-sharing to form two-dimensional layers. The two-dimensio nal layers are stacked along [100] direction and form three-dimensional structu re via hydrogen bonding. CCDC: 181925. |
