Rb2PdAs2 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 Pd(1) and six equivalent As(1) atoms. In the second Rb site, Rb(2) is bonded in a 6-coordinate geometry to six equivalent As(1) atoms. Pd(1) is bonded in a 6-coordinate geometry to two equivalent Rb(1) and four equivalent As(1) atoms. As(1) is bonded in a 9-coordinate geometry to three equivalent Rb(1), three equivalent Rb(2), two equivalent Pd(1), and one As(1) atom.
Rb2PdAs2 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 Pd(1) and six equivalent As(1) atoms. Both Rb(1)-Pd(1) bond lengths are 3.43 Å. There are two shorter (3.52 Å) and four longer (3.63 Å) Rb(1)-As(1) bond lengths. In the second Rb site, Rb(2) is bonded in a 6-coordinate geometry to six equivalent As(1) atoms. There are two shorter (3.56 Å) and four longer (3.80 Å) Rb(2)-As(1) bond lengths. Pd(1) is bonded in a 6-coordinate geometry to two equivalent Rb(1) and four equivalent As(1) atoms. All Pd(1)-As(1) bond lengths are 2.51 Å. As(1) is bonded in a 9-coordinate geometry to three equivalent Rb(1), three equivalent Rb(2), two equivalent Pd(1), and one As(1) atom. The As(1)-As(1) bond length is 2.41 Å.
