The material described by RbPdCuSe5 crystallizes in the monoclinic P2_1/m space group. Rb(1) is bonded in a 9-coordinate geometry to one Se(1), four equivalent Se(2), and four equivalent Se(4) atoms. Pd(1) is bonded in a square co-planar geometry to two equivalent Se(2) and two equivalent Se(3) atoms. Cu(1) is bonded to one Se(1), one Se(3), and two equivalent Se(2) atoms to form CuSe4 tetrahedra that share  a cornercorner with one Se(4)Rb4Se trigonal bipyramid. There are four inequivalent Se sites. In the first Se site, Se(1) is bonded in a 4-coordinate geometry to one Rb(1), one Cu(1), and two equivalent Se(2) atoms. In the second Se site, Se(2) is bonded in a 5-coordinate geometry to two equivalent Rb(1), one Pd(1), one Cu(1), and one Se(1) atom. In the third Se site, Se(3) is bonded to two equivalent Pd(1), one Cu(1), and one Se(4) atom to form distorted corner-sharing SeCuPd2Se tetrahedra. In the fourth Se site, Se(4) is bonded to four equivalent Rb(1) and one Se(3) atom to form distorted SeRb4Se trigonal bipyramids that share  a cornercorner with one Cu(1)Se4 tetrahedra, corners with four equivalent Se(4)Rb4Se trigonal bipyramids, and edges with four equivalent Se(4)Rb4Se trigonal bipyramids. is represented by the CIF file [CIF]
