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 4-coordinate geometry to two equivalent Au(1) and two equivalent Sn(1) atoms. In the second Rb site, Rb(2) is bonded in a 3-coordinate geometry to one Sn(2) and two equivalent Sn(1) atoms. Au(1) is bonded in a 6-coordinate geometry to two equivalent Rb(1), 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 4-coordinate geometry to one Rb(1), two equivalent Rb(2), and one Au(1) atom. In the second Sn site, Sn(2) is bonded in a 2-coordinate geometry to one Rb(2) and one Au(1) atom.
