Materials Data on K2Pd(NO3)4 by Materials Project

K2Pd(NO3)4 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. K1+ is bonded in a 7-coordinate geometry to ten O2- atoms. There are a spread of K–O bond distances ranging from 2.77–3.49 Å. Pd2+ is bonded in a square co-planar geometry to four O2- atoms. There are two shorter (2.04 Å) and two longer (2.05 Å) Pd–O bond lengths. There are two inequivalent N5+ sites. In the first 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 1.24–1.33 Å. 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 single-bond geometry to two equivalent K1+ and one N5+ atom. In the second O2- site, O2- is bonded in a 3-coordinate geometry to one K1+, one Pd2+, and one N5+ atom. In the third O2- site, O2- is bonded in a single-bond geometry to one K1+ and one N5+ atom. In the fourth O2- site, O2- is bonded in a distorted single-bond geometry to three equivalent K1+ and one N5+ atom. In the fifth O2- site, O2- is bonded in a 2-coordinate geometry to one K1+, one Pd2+, and one N5+ atom. In the sixth O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent K1+ and one N5+ atom.
