[edit] Summary

Description	An image of the crystal structure of cubic ZrW2O8 with polyhedral represntation of structural groups. ZrO6 octahedra are shown in green, and WO4 tetrahedra in red. The oxygen atoms at the vertices of polyhedra are shown as red spheres.
Source	This image is my own work. The crsytal structure used for production of this image was taken from the Inorganic Crystal Structure Database, and was originally published in the article: "Evans, J.S.O.;David, W.I.F.;Sleight, A.W. (1999), Acta Crystallographica B (39,1983-) 55, 333-340, Structural investigation of the Negative-thermal-expansion material Zr W2 O8"
