The compound described by RbReCl4 crystallizes in the orthorhombic Cmcm space group. There are two inequivalent Rb sites. In the first Rb site, Rb(1) is bonded in a 8-coordinate geometry to two equivalent Cl(1), two equivalent Cl(3), two equivalent Cl(4), and two equivalent Cl(5) atoms. In the second Rb site, Rb(2) is bonded in a 9-coordinate geometry to one Cl(2), two equivalent Cl(1), two equivalent Cl(5), and four equivalent Cl(3) atoms. There are two inequivalent Re sites. In the first Re site, Re(1) is bonded to one Cl(1), one Cl(4), one Cl(6), and two equivalent Cl(3) atoms to form distorted corner-sharing ReCl5 square pyramids. In the second Re site, Re(2) is bonded to one Cl(2), two equivalent Cl(4), and two equivalent Cl(5) atoms to form distorted corner-sharing ReCl5 square pyramids. There are six inequivalent Cl sites. In the first Cl site, Cl(5) is bonded in a distorted single-bond geometry to one Rb(2), two equivalent Rb(1), and one Re(2) atom. In the second Cl site, Cl(6) is bonded in a 2-coordinate geometry to two equivalent Re(1) atoms. In the third Cl site, Cl(1) is bonded to one Rb(2), two equivalent Rb(1), and one Re(1) atom to form a mixture of corner and edge-sharing ClRb3Re tetrahedra. In the fourth Cl site, Cl(2) is bonded in a linear geometry to one Rb(2) and one Re(2) atom. In the fifth Cl site, Cl(3) is bonded in a 3-coordinate geometry to one Rb(1), one Rb(2), and one Re(1) atom. In the sixth Cl site, Cl(4) is bonded in a 4-coordinate geometry to two equivalent Rb(1), one Re(1), and one Re(2) atom. is represented by the CIF file [CIF]
