Materials Data on NaH8Rh(N2O3)4 by Materials Project
Na(NO2)6Rh(NH4)2 is Heusler structured and crystallizes in the cubic Fm-3 space group. The structure is zero-dimensional and consists of eight ammonium molecules, four rhodium molecules, and four Na(NO2)6 clusters. In each Na(NO2)6 cluster, Na1+ is bonded in a cuboctahedral geometry to twelve equivalent O2- atoms. All Na–O bond lengths are 2.92 Å. N+1.50+ is bonded in a bent 120 degrees geometry to two equivalent O2- atoms. Both N–O bond lengths are 1.25 Å. O2- is bonded in a single-bond geometry to one Na1+ and one N+1.50+ atom.
