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.
