CRYSTAL STRUCTRURE OF POTASSIUM BIS- (11-MOLYBDOSILICA-TO)DYSPROSATE(Ⅲ)

<正> Crystal of the title complex K10H3[Dy(SiMo11O39)2]·29H2O(Mr= 4331.85) is monoclinic with space group P21/n,a= 17. 256(1) ,b = 26. 817(1) ,c = 21.797(1) A,β= 104. 39(1)°, V = 9770. 2 (A3), Z= 4, F (000) = 8140, and Dc= 2. 94g/cm3. The Dy3+ is coordinated by eight oxygen atoms from two tetradentate (SiMo11O39)8- ligands,forming a square antiprism. The cation K+ is coordinated by oxygen atoms from heteropoly ligands (SiMo11O39)8- and water molecules, the number of atoms that are coordinated to the potassium atoms can be divided into four groups:six,seven, eight and nine.
