Materials Data on NaIr(N2O3)4 by Materials Project
IrNa(NO2)6N2 is Heusler structured and crystallizes in the cubic Fm-3 space group. The structure is zero-dimensional and consists of eight ammonia molecules, four iridium 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 2.80 Å. N+2.50+ is bonded in a bent 120 degrees geometry to two equivalent O2- atoms. Both N–O bond lengths are 1.24 Å. O2- is bonded in a distorted single-bond geometry to one Na1+ and one N+2.50+ atom.
