Materials Data on Rb3Ni2(NO3)7 by Materials Project
Rb3Ni2(NO3)7 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. there are two inequivalent Rb1+ sites. In the first Rb1+ site, Rb1+ is bonded in a 12-coordinate geometry to twelve O2- atoms. There are a spread of Rb–O bond distances ranging from 3.04–3.33 Å. In the second Rb1+ site, Rb1+ is bonded in a 11-coordinate geometry to eleven O2- atoms. There are a spread of Rb–O bond distances ranging from 2.91–3.34 Å. Ni2+ is bonded in an octahedral geometry to six O2- atoms. There are a spread of Ni–O bond distances ranging from 2.07–2.22 Å. There are four 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 1.24–1.29 Å. In the second N5+ site, N5+ is bonded in a trigonal planar geometry to three O2- atoms. There is one shorter (1.23 Å) and two longer (1.29 Å) N–O bond length. In the third N5+ site, N5+ is bonded in a trigonal planar geometry to three O2- atoms. There is one shorter (1.24 Å) and two longer (1.28 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 (1.31 Å) N–O bond length. There are eleven inequivalent O2- sites. In the first O2- site, O2- is bonded in a single-bond geometry to two equivalent Rb1+ and one N5+ atom. In the second O2- site, O2- is bonded in a 2-coordinate geometry to two Rb1+, one Ni2+, and one N5+ atom. In the third O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Rb1+ and one N5+ atom. In the fourth O2- site, O2- is bonded in a 2-coordinate geometry to one Rb1+, one Ni2+, and one N5+ atom. In the fifth O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Rb1+ and one N5+ atom. In the sixth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to two equivalent Rb1+, one Ni2+, and one N5+ atom. In the seventh O2- site, O2- is bonded in a bent 120 degrees geometry to one Ni2+ and one N5+ atom. In the eighth O2- site, O2- is bonded in a distorted L-shaped geometry to two Rb1+, one Ni2+, and one N5+ atom. In the ninth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Rb1+, one Ni2+, and one N5+ atom. In the tenth O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Rb1+ and one N5+ atom. In the eleventh O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Rb1+ and one N5+ atom.
