The material structure described by KAu4Sn2 crystallizes in the tetragonal I-4c2 space group. K(1) is bonded in a 8-coordinate geometry to eight equivalent Au(1) atoms. Au(1) is bonded in a 10-coordinate geometry to two equivalent K(1), four equivalent Au(1), and four equivalent Sn(1) atoms. Sn(1) is bonded in a 8-coordinate geometry to eight equivalent Au(1) atoms. is represented by the CIF card [CIF]
