Materials Data on K2H14Rh2N12O17 by Materials Project

K2(NO2)7(Rh)2(NH3)4NO2H2O crystallizes in the triclinic P-1 space group. The structure is two-dimensional and consists of eight ammonia molecules; two hydroxylamine, n-hydroxy- molecules; four rhodium molecules; two water molecules; and one K2(NO2)7 sheet oriented in the (0, 0, 1) direction. In the K2(NO2)7 sheet, there are two inequivalent K1+ sites. In the first K1+ site, K1+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of K–O bond distances ranging from 2.66–3.30 Å. In the second K1+ site, K1+ is bonded in a 10-coordinate geometry to ten O2- atoms. There are a spread of K–O bond distances ranging from 2.84–3.33 Å. There are seven inequivalent N1+ sites. In the first N1+ site, N1+ is bonded in a bent 120 degrees geometry to two O2- atoms. There is one shorter (1.24 Å) and one longer (1.26 Å) N–O bond length. In the second N1+ site, N1+ is bonded in a bent 120 degrees geometry to two O2- atoms. Both N–O bond lengths are 1.25 Å. In the third N1+ site, N1+ is bonded in a bent 120 degrees geometry to two O2- atoms. Both N–O bond lengths are 1.25 Å. In the fourth N1+ site, N1+ is bonded in a bent 120 degrees geometry to two O2- atoms. Both N–O bond lengths are 1.25 Å. In the fifth N1+ site, N1+ is bonded in a bent 120 degrees geometry to two O2- atoms. Both N–O bond lengths are 1.25 Å. In the sixth N1+ site, N1+ is bonded in a bent 120 degrees geometry to two O2- atoms. Both N–O bond lengths are 1.25 Å. In the seventh N1+ site, N1+ is bonded in a bent 120 degrees geometry to two O2- atoms. Both N–O bond lengths are 1.25 Å. There are fourteen inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to two K1+ and one N1+ atom. In the second O2- site, O2- is bonded in a single-bond geometry to one K1+ and one N1+ atom. In the third O2- site, O2- is bonded in a single-bond geometry to one K1+ and one N1+ atom. In the fourth O2- site, O2- is bonded in a single-bond geometry to one N1+ atom. In the fifth O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent K1+ and one N1+ atom. In the sixth O2- site, O2- is bonded in a single-bond geometry to one N1+ atom. In the seventh O2- site, O2- is bonded in a distorted single-bond geometry to two K1+ and one N1+ atom. In the eighth O2- site, O2- is bonded in a distorted single-bond geometry to three K1+ and one N1+ atom. In the ninth O2- site, O2- is bonded in a single-bond geometry to one K1+ and one N1+ atom. In the tenth O2- site, O2- is bonded in a distorted single-bond geometry to one K1+ and one N1+ atom. In the eleventh O2- site, O2- is bonded in a distorted single-bond geometry to two K1+ and one N1+ atom. In the twelfth O2- site, O2- is bonded in a single-bond geometry to one K1+ and one N1+ atom. In the thirteenth O2- site, O2- is bonded in a distorted single-bond geometry to two K1+ and one N1+ atom. In the fourteenth O2- site, O2- is bonded in a distorted single-bond geometry to one K1+ and one N1+ atom.
