摘要
A new double alkali metal borate,LiRbB8O13,has been obtained in the sealed system.Its structure consists of two kinds of independent interpenetrating 3D frameworks composed of the fundamental building block,[B8O16]8–.It crystallizes in the P21/c space group with a=10.950(6),b=7.689(4),c=11.375(7)?,β=96.653(7)°,V=951.2(9)?3,Z=4,F(000)=736,Dc=2.702 g/cm3,Mr=386.89 andμ=5.289 mm–1.The final R=0.0547 and w R=0.1224.The UV-Vis-NIR diffuse reflectance spectrum,infrared spectrum and the first-principle theoretical studies show that the title compound possesses a short cut-off edge and large birefringence.
