The compound described by Rb2Zn5Sb4 crystallizes in the orthorhombic Cmcm space group. Rb(1) is bonded in a 6-coordinate geometry to two equivalent Zn(1), two equivalent Sb(1), and two equivalent Sb(2) atoms. There are three inequivalent Zn sites. In the first Zn site, Zn(1) is bonded in a 4-coordinate geometry to two equivalent Rb(1), two equivalent Sb(1), and two equivalent Sb(2) atoms. In the second Zn site, Zn(2) is bonded in a 4-coordinate geometry to two equivalent Sb(1) and two equivalent Sb(2) atoms. In the third Zn site, Zn(3) is bonded in a 4-coordinate geometry to two equivalent Sb(1) and two equivalent Sb(2) atoms. There are two inequivalent Sb sites. In the first Sb site, Sb(2) is bonded in a 7-coordinate geometry to two equivalent Rb(1), one Zn(3), two equivalent Zn(1), and two equivalent Zn(2) atoms. In the second Sb site, Sb(1) is bonded in a 5-coordinate geometry to two equivalent Rb(1), one Zn(3), two equivalent Zn(1), and two equivalent Zn(2) atoms. is represented by the CIF file [CIF]
