The material described by Gd2Au2Sn crystallizes in the tetragonal P4/mbm space group. Gd(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 Gd(1), one Au(1), and two equivalent Sn(1) atoms. Sn(1) is bonded to eight equivalent Gd(1) and four equivalent Au(1) atoms to form a mixture of corner and face-sharing SnGd8Au4 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
