The crystal structure of Pb<sub>3</sub>BiV<sub>3</sub>O<sub>12</sub> was solved using single-crystal X-ray diffraction technique. The compound crystallizes in the cubic system I43d (No. 220) with eulytite structure with <i>a</i> = 10.7490(7) Å, <i>V</i> = 1241.95(14) Å<sup>3</sup> and <i>Z</i> = 4. The final <i>R</i><sub>1</sub> value of 0.0198 (<i>w</i><i>R</i><sub>2</sub>=0.0384) was achieved for 359 independent reflections during the structure refinement. The Pb<sup>2+</sup> and Bi<sup>3+</sup> cations occupy the special position (<i>16c</i>) while the oxygen anions occupy the general position (<i>48e</i>) 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 [VO<sub>4</sub>]<sup>3−</sup> tetrahedra units, generating a eulytite-type network in the crystal lattice.< Réduire
