Materials Data on Sm2(N4O9)3 by Materials Project

Sm2(N4O9)3 crystallizes in the cubic P4_132 space group. The structure is three-dimensional. Sm3+ is bonded to twelve O2- atoms to form corner-sharing SmO12 cuboctahedra. There are a spread of Sm–O bond distances ranging from 2.52–2.70 Å. There are three inequivalent N4+ sites. In the first N4+ site, N4+ is bonded in a linear geometry to two equivalent O2- atoms. Both N–O bond lengths are 1.91 Å. In the second N4+ site, N4+ is bonded in a trigonal planar geometry to three O2- atoms. There are a spread of N–O bond distances ranging from 1.26–1.28 Å. In the third N4+ site, N4+ is bonded in a trigonal planar geometry to three O2- atoms. There is two shorter (1.25 Å) and one longer (1.31 Å) N–O bond length. There are five inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to one Sm3+ and one N4+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to one Sm3+ and one N4+ atom. In the third O2- site, O2- is bonded in a water-like geometry to two N4+ atoms. In the fourth O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Sm3+ and one N4+ atom. In the fifth O2- site, O2- is bonded in a single-bond geometry to one Sm3+ and one N4+ atom.
