The crystal structure of eulytite Pb3BiV3O12
The crystal structure of Pb3BiV3O12 was solved using single-crystal X-ray diffraction technique. The compound crystallizes in the cubic system 1 (4) over bar 3d (No. 220) with eulytite structure with a = 10.7490(7) angstrom, V = 1241.95(14) angstrom(3) and Z = 4. The final R-1 value of 0.0198 (wR(2) = 0.0384) was achieved for 359 independent reflections during the structure refinement. The Pb2+ and Bi3+ cations occupy the special position ( 16c) while the oxygen anions occupy the general position (48e) in the crystal structure. Unlike many other eulytite compounds, all the crystallographic positions are fully occupied. The structure consists of edge-shared Pb/Bi octahedra linked at the corners to independent [VO4](3-) tetrahedra units, generating a eulytite-type network in the crystal lattice.
