Abstract: The present paper describes the crystal structure of the title compound H6SiMo2γMo10иO10·10H2O prepared by electrolysis.The complex crystallizes in the triclinic space group P1 with a=1.4077(3) nm,b=1.4176(3) nm,c=1.3752(2) nm;α=111.04(1)°,β=93.99(1)°,7=119.09(1)°;Z=2.9005 independent reflections were collected.The structure was solved by direct method and refined by block diagonal-matrix least-squares to R=0.052 for 6287 reflections.The structure of the heteropoly blue retains the original structure of its parent acid basically,but some octahedra change distortedly.

Key words: α-Keggin structure, Heteropoly blue, Crystal structure
