title: Materials Data on Sm(NO3)3 by Materials Project

description: Sm(NO3)3 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. there are three inequivalent Sm3+ sites. In the first Sm3+ site, Sm3+ is bonded to twelve O2- atoms to form corner-sharing SmO12 cuboctahedra. There are a spread of Sm–O bond distances ranging from 2.59–2.63 Å. In the second Sm3+ site, Sm3+ is bonded to twelve O2- atoms to form distorted corner-sharing SmO12 cuboctahedra. There are a spread of Sm–O bond distances ranging from 2.57–2.76 Å. In the third Sm3+ site, Sm3+ is bonded in a 11-coordinate geometry to eleven O2- atoms. There are a spread of Sm–O bond distances ranging from 2.50–2.78 Å. There are six inequivalent N5+ sites. In the first N5+ site, N5+ is bonded in a trigonal planar geometry to three O2- atoms. There is two shorter (1.25 Å) and one longer (1.30 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 1.24–1.30 Å. In the third N5+ site, N5+ is bonded in a trigonal planar geometry to three O2- atoms. There is two shorter (1.25 Å) and one longer (1.30 Å) N–O bond length. In the fourth N5+ site, N5+ is bonded in a trigonal planar geometry to three O2- atoms. There is two shorter (1.25 Å) and one longer (1.29 Å) N–O bond length. In the fifth N5+ site, N5+ is bonded in a trigonal planar geometry to three O2- atoms. There is one shorter (1.25 Å) and two longer (1.28 Å) N–O bond length. In the sixth 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 1.25–1.30 Å. There are eighteen inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to one Sm3+ and one N5+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to two Sm3+ and one N5+ atom.

In the fourth O2- site, O2- is bonded in a distorted single-bond geometry to one Sm3+ and one N5+ atom. In the fifth O2- site, O2- is bonded in a distorted single-bond geometry to one Sm3+ and one N5+ atom. In the sixth O2- site, O2- is bonded in a distorted single-bond geometry to two Sm3+ and one N5+ atom. In the seventh O2- site, O2- is bonded in a distorted single-bond geometry to one Sm3+ and one N5+ atom. In the eighth O2- site, O2- is bonded in a distorted single-bond geometry to one Sm3+ and one N5+ atom. In the ninth O2- site, O2- is bonded in a distorted single-bond geometry to one Sm3+ and one N5+ atom. In the tenth O2- site, O2- is bonded in a distorted single-bond geometry to two Sm3+ and one N5+ atom. In the eleventh O2- site, O2- is bonded in a distorted single-bond geometry to one Sm3+ and one N5+ atom.
