The material structure described by Rb2Pd3Se4 crystallizes in the orthorhombic Fddd space group. Rb(1) is bonded in a 14-coordinate geometry to two equivalent Pd(2), four equivalent Pd(1), and eight equivalent Se(1) atoms. There are two inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a distorted square co-planar geometry to four equivalent Rb(1) and four equivalent Se(1) atoms. In the second Pd site, Pd(2) is bonded in a distorted square co-planar geometry to four equivalent Rb(1) and four equivalent Se(1) atoms. Se(1) is bonded in a 7-coordinate geometry to four equivalent Rb(1), one Pd(2), and two equivalent Pd(1) atoms. is represented by the CIF file [CIF]
