The material structure described by Na2Pd(SeO4)2 crystallizes in the triclinic P-1 space group. Na(1) is bonded in a 6-coordinate geometry to one O(1), one O(2), two equivalent O(3), and two equivalent O(4) atoms. Pd(1) is bonded in a square co-planar geometry to two equivalent O(1) and two equivalent O(2) atoms. Se(1) is bonded in a tetrahedral geometry to one O(1), one O(2), one O(3), and one O(4) atom. There are four inequivalent O sites. In the first O site, O(1) is bonded in a trigonal planar geometry to one Na(1), one Pd(1), and one Se(1) atom. In the second O site, O(2) is bonded in a distorted trigonal planar geometry to one Na(1), one Pd(1), and one Se(1) atom. In the third O site, O(3) is bonded in a 3-coordinate geometry to two equivalent Na(1) and one Se(1) atom. In the fourth O site, O(4) is bonded in a distorted trigonal planar geometry to two equivalent Na(1) and one Se(1) atom. is represented by the CIF file [CIF]
