The compound described by Rb2ZnCl4 crystallizes in the orthorhombic Pna2_1 space group. There are two inequivalent Rb sites. In the first Rb site, Rb(1) is bonded in a 8-coordinate geometry to one Cl(3), two equivalent Cl(1), two equivalent Cl(2), and three equivalent Cl(4) atoms. In the second Rb site, Rb(2) is bonded in a 9-coordinate geometry to two equivalent Cl(1), two equivalent Cl(2), two equivalent Cl(4), and three equivalent Cl(3) atoms. Zn(1) is bonded in a tetrahedral geometry to one Cl(1), one Cl(2), one Cl(3), and one Cl(4) atom. There are four inequivalent Cl sites. In the first Cl site, Cl(1) is bonded in a distorted single-bond geometry to two equivalent Rb(1), two equivalent Rb(2), and one Zn(1) atom. In the second Cl site, Cl(2) is bonded in a distorted single-bond geometry to two equivalent Rb(1), two equivalent Rb(2), and one Zn(1) atom. In the third Cl site, Cl(3) is bonded in a 1-coordinate geometry to one Rb(1), three equivalent Rb(2), and one Zn(1) atom. In the fourth Cl site, Cl(4) is bonded in a 6-coordinate geometry to two equivalent Rb(2), three equivalent Rb(1), and one Zn(1) atom. is represented by the CIF file [CIF]
