Materials Data on As2PbO6 by Materials Project
Pb(As2O6) crystallizes in the trigonal P-31m space group. The structure is three-dimensional. Pb2+ is bonded to six equivalent O2- atoms to form PbO6 octahedra that share corners with twelve equivalent AsO6 octahedra. The corner-sharing octahedral tilt angles are 53°. All Pb–O bond lengths are 2.58 Å. As5+ is bonded to six equivalent O2- atoms to form AsO6 octahedra that share corners with six equivalent PbO6 octahedra and edges with three equivalent AsO6 octahedra. The corner-sharing octahedral tilt angles are 53°. All As–O bond lengths are 1.87 Å. O2- is bonded in a 2-coordinate geometry to one Pb2+ and two equivalent As5+ atoms.
