The material structure described by Rb2Cd5As4 crystallizes in the orthorhombic Cmcm space group. Rb(1) is bonded in a 6-coordinate geometry to two equivalent Cd(1), two equivalent As(1), and two equivalent As(2) atoms. There are three inequivalent Cd sites. In the first Cd site, Cd(1) is bonded in a 4-coordinate geometry to two equivalent Rb(1), two equivalent As(1), and two equivalent As(2) atoms. In the second Cd site, Cd(2) is bonded to two equivalent As(1) and two equivalent As(2) atoms to form distorted edge-sharing CdAs4 tetrahedra. In the third Cd site, Cd(3) is bonded in a 4-coordinate geometry to two equivalent As(1) and two equivalent As(2) atoms. There are two inequivalent As sites. In the first As site, As(2) is bonded in a 7-coordinate geometry to two equivalent Rb(1), one Cd(3), two equivalent Cd(1), and two equivalent Cd(2) atoms. In the second As site, As(1) is bonded in a 5-coordinate geometry to two equivalent Rb(1), one Cd(3), two equivalent Cd(1), and two equivalent Cd(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
