摘要：

K6H7 [Dy(SiMo6W5O39)2] 10H2O, Mr= 4878. 5, is triclinic, sapcegroup P1 with a= 22. 697(5) A; b= 12. 835(4) A; c= 18. 216(6) A; a= 90. 56(2); β= 98. 24(2); γ= 90. 51 (2)°；V= 5251 (2) A3； Z= 2, Dc= 3.08 g/cm3; F(000) = 4321; S = 1. 550, μ= 183.65 cm-1. Refinement resulted in a final R of0.091, based on 7816 with I>3δ independent renections. The structure contains discrete [Dy (SiW5Mo6O39) 2] 13 - anions. The orientations fo the W and Mo atoms are random in the crystal. The MO6 octahedron and SiO4 tetrahedron are somewhat distorted.
