The compound described by Rb2Pd3Se2 crystallizes in the orthorhombic Fddd space group. Rb(1) is bonded in a 2-coordinate geometry to one Pd(1), one Pd(2), and two equivalent Se(1) atoms. There are two inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a distorted linear geometry to two equivalent Rb(1), two equivalent Pd(2), and two equivalent Se(1) atoms. In the second Pd site, Pd(2) is bonded in a 3-coordinate geometry to one Rb(1), one Pd(1), and two equivalent Se(1) atoms. Se(1) is bonded in a 5-coordinate geometry to two equivalent Rb(1), one Pd(1), and two equivalent Pd(2) atoms. is represented by the CIF card [CIF]
