The structure described by Tb2Au2Sn crystallizes in the tetragonal P4/mbm space group. Tb(1) is bonded in a 6-coordinate geometry to six equivalent Au(1) and four equivalent Sn(1) atoms. Au(1) is bonded in a 9-coordinate geometry to six equivalent Tb(1), one Au(1), and two equivalent Sn(1) atoms. Sn(1) is bonded to eight equivalent Tb(1) and four equivalent Au(1) atoms to form a mixture of face and corner-sharing SnTb8Au4 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
