Materials Data on Na2Pd(NO3)4 by Materials Project
Na2Pd(NO3)4 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Na1+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Na–O bond distances ranging from 2.44–2.92 Å. Pd2+ is bonded in a square co-planar geometry to four O2- atoms. All Pd–O bond lengths are 2.04 Å. There are two inequivalent N5+ sites. In the first N5+ site, N5+ is bonded in a trigonal planar geometry to three O2- atoms. There is two shorter (1.24 Å) and one longer (1.33 Å) N–O bond length. In the second N5+ site, N5+ is bonded in a trigonal planar geometry to three O2- atoms. There are a spread of N–O bond distances ranging from 1.24–1.32 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal planar geometry to one Na1+, one Pd2+, and one N5+ atom. In the second O2- site, O2- is bonded in a bent 150 degrees geometry to one Na1+ and one N5+ atom. In the third O2- site, O2- is bonded in a 2-coordinate geometry to one Na1+ and one N5+ atom. In the fourth O2- site, O2- is bonded in a bent 120 degrees geometry to one Pd2+ and one N5+ atom. In the fifth O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Na1+ and one N5+ atom. In the sixth O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Na1+ and one N5+ atom.
