Rb3AuSn4 crystallizes in the orthorhombic Pmmn space group. There are two inequivalent Rb sites. In the first Rb site, Rb(1) is bonded in a 6-coordinate geometry to two equivalent Au(1) and four equivalent Sn(2) atoms. In the second Rb site, Rb(2) is bonded in a 9-coordinate geometry to one Au(1), four equivalent Sn(1), and four equivalent Sn(2) atoms. Au(1) is bonded in a 8-coordinate geometry to two equivalent Rb(1), two equivalent Rb(2), two equivalent Sn(1), and two equivalent Sn(2) atoms. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 1-coordinate geometry to four equivalent Rb(2) and one Au(1) atom. In the second Sn site, Sn(2) is bonded in a 1-coordinate geometry to two equivalent Rb(1), four equivalent Rb(2), and one Au(1) atom.
