Materials Data on Ge3(WO6)2 by Materials Project
Ge3(WO6)2 crystallizes in the cubic Ia-3d space group. The structure is three-dimensional. W6+ is bonded to six equivalent O2- atoms to form WO6 octahedra that share corners with six equivalent GeO4 tetrahedra. All W–O bond lengths are 1.95 Å. Ge4+ is bonded to four equivalent O2- atoms to form GeO4 tetrahedra that share corners with four equivalent WO6 octahedra. The corner-sharing octahedral tilt angles are 42°. All Ge–O bond lengths are 1.76 Å. O2- is bonded in a distorted bent 150 degrees geometry to one W6+ and one Ge4+ atom.
