Abstract: The crystal structure of K8H(BW11O39)·13H2O has been determined by X-ray diffrac-tometry on the four-circle diffractometer. The ctystal is cubic with the space group P43m and a=10.710(1)Å,V=1228.58Å3,Do=4.39gcm-3,Dc=4.42gcm-3for Z=1.The structureof(BW11O39)-9 anion belongs to an unsaturated α-Keggin type, with B atom being on thecenter of O2 tetrahedron. The IR and Raman spectra of the compound have also been measured and discussed.

Key words: Crystal, structure, Heterop1y borotungstic acid, Vibration spectrum
