Materials Data on Na2Pd(SeO4)2 by Materials Project
Na2Pd(SeO4)2 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. Na1+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Na–O bond distances ranging from 2.39–2.83 Å. Pd4+ is bonded in a square co-planar geometry to four O2- atoms. All Pd–O bond lengths are 2.04 Å. Se5+ is bonded in a tetrahedral geometry to four O2- atoms. There are a spread of Se–O bond distances ranging from 1.65–1.73 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a trigonal planar geometry to one Na1+, one Pd4+, and one Se5+ atom. In the second O2- site, O2- is bonded in a distorted trigonal planar geometry to one Na1+, one Pd4+, and one Se5+ atom. In the third O2- site, O2- is bonded in a 2-coordinate geometry to two equivalent Na1+ and one Se5+ atom. In the fourth O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Na1+ and one Se5+ atom.
