摘要
标题化合物K_8H〔BW_(11)O_(39)〕·13H_2O属立方晶系,空间群P43m,a=10.710(1)A,V=1228.58A^3,Z=1;D_O=4.39g·cm^(-3),D_c=4.42g·cm^(-3)。(BW_(11)O_(3.9)^(9-)离子属于不饱和α-Keggin型结构,B原子位于O_a四面体的中心。测定并研究了化合物的IR和Raman光谱性质。
The crystal structure of K_8H(BW_(11)O_(39)).13H_2 O has been determined by X-ray diffrac-tometry on the four-circle diffractometer. The ctystal is cubic with the space group P43mand a=10.710(1)A,V=1228.58A^3,Do=4.39gcm^(- 3),Dc=4.42gcm^(-3)for Z=1.The structureof(BW_(11)O_(39))^(-9) anion belongs to an unsaturated α-Keggin type, with B atom being on thecenter of O. tetrahedron. The IR and Raman spectra of the compound have also been mea-sured and discussed.
