The compound described by Tb5Au2Bi crystallizes in the tetragonal I4/mcm space group. There are two inequivalent Tb sites. In the first Tb site, Tb(1) is bonded in a distorted trigonal planar geometry to one Au(1) and two equivalent Bi(1) atoms. In the second Tb site, Tb(2) is bonded in a square co-planar geometry to four equivalent Au(1) atoms. Au(1) is bonded to two equivalent Tb(1), two equivalent Tb(2), and one Au(1) atom to form distorted corner-sharing AuTb4Au trigonal bipyramids. Bi(1) is bonded in a 8-coordinate geometry to eight equivalent Tb(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
