K(Au2Sn3)2 crystallizes in the orthorhombic Fddd space group. K(1) is bonded in a 14-coordinate geometry to four equivalent Au(1), four equivalent Au(2), two equivalent Sn(2), and four equivalent Sn(1) atoms. There are two inequivalent Au sites. In the first Au site, Au(1) is bonded in a 9-coordinate geometry to two equivalent K(1), one Au(2), two equivalent Sn(2), and four equivalent Sn(1) atoms. In the second Au site, Au(2) is bonded in a 9-coordinate geometry to two equivalent K(1), one Au(1), two equivalent Sn(2), and four equivalent Sn(1) atoms. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 5-coordinate geometry to one K(1), two equivalent Au(1), and two equivalent Au(2) atoms. In the second Sn site, Sn(2) is bonded in a 4-coordinate geometry to one K(1), two equivalent Au(1), and two equivalent Au(2) atoms.
