Abstract: Molybdosilicic heteropoly complex with dysprosium and its single crystal were prepared. The crystal structure with space group .P21/n was determined by means of X-ray single crystal structure analysis method, the unit cell parameters are as follows: a=17. 256(1)Å, b=26. 817(1)Å, c=21.797(1)Å,β=104. 39(1)°,V=9770. 2Å3. Z=4, F(000)=8140,Dc=2. 94 g/cm3. The results show that the dysprosium atom is coordinated to eight oxygen atoms which are from two tetraden-tate ligands SiMo11O398-. The point-group for its local symmetry is pseudonym D4d(staggered). Potassium atoms are coordinated to six,seven, eight or nine O-atoms. Vibration spectrum of the title complex was also discussed.
