Materials Data on RhN5O7 by Materials Project

(RhNO)2N2(NO2)6 crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of four ammonia molecules, twelve nitrous acid molecules, and two RhNO clusters. In each RhNO cluster, Rh3+ is bonded in a distorted trigonal non-coplanar geometry to one N+2.20+ and two equivalent O2- atoms. The Rh–N bond length is 1.65 Å. There is one shorter (1.96 Å) and one longer (1.97 Å) Rh–O bond length. N+2.20+ is bonded in a single-bond geometry to one Rh3+ atom. O2- is bonded in a water-like geometry to two equivalent Rh3+ atoms.

Materials Data on Rh(N2O3)3 by Materials Project

Rh(N2O3)3 crystallizes in the trigonal P3 space group. The structure is zero-dimensional and consists of one nsc241243 molecule. Rh4+ is bonded in a 6-coordinate geometry to three equivalent N+2.33+ and three equivalent O2- atoms. All Rh–N bond lengths are 1.82 Å. All Rh–O bond lengths are 2.21 Å. There are two inequivalent N+2.33+ sites. In the first N+2.33+ site, N+2.33+ is bonded in a trigonal planar geometry to three O2- atoms. There are a spread of N–O bond distances ranging from 1.23–1.34 Å. In the second N+2.33+ site, N+2.33+ is bonded in a distorted single-bond geometry to one Rh4+ atom. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Rh4+ and one N+2.33+ atom. In the second O2- site, O2- is bonded in a single-bond geometry to one N+2.33+ atom. In the third O2- site, O2- is bonded in a single-bond geometry to one N+2.33+ atom.
