The crystal structure described by Bi is alpha Po structured and crystallizes in the monoclinic P2_1/m space group. There are two inequivalent Bi sites. In the first Bi site, Bi(1) is bonded to six equivalent Bi(2) atoms to form a mixture of edge and corner-sharing BiBi6 octahedra. The corner-sharing octahedral tilt angles range from 0-1°. In the second Bi site, Bi(2) is bonded to six equivalent Bi(1) atoms to form a mixture of edge and corner-sharing BiBi6 octahedra. The corner-sharing octahedral tilt angles range from 0-1°. is represented by the CIF file [CIF]
