Materials Data on K2Pt(NO2)4 by Materials Project

K2Pt(NO2)4 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional and consists of four platinum molecules and one K(NO2)2 framework. In the K(NO2)2 framework, there are two inequivalent K1+ sites. In the first K1+ site, K1+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of K–O bond distances ranging from 2.81–3.28 Å. In the second 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 2.74–3.28 Å. There are four inequivalent N3+ sites. In the first N3+ site, N3+ is bonded in a bent 120 degrees geometry to two O2- atoms. Both N–O bond lengths are 1.25 Å. In the second N3+ site, N3+ is bonded in a bent 120 degrees geometry to two O2- atoms. There is one shorter (1.25 Å) and one longer (1.26 Å) N–O bond length. In the third N3+ site, N3+ is bonded in a bent 120 degrees geometry to two O2- atoms. Both N–O bond lengths are 1.25 Å. In the fourth N3+ site, N3+ is bonded in a bent 120 degrees geometry to two O2- atoms. Both N–O bond lengths are 1.25 Å. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to three K1+ and one N3+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent K1+ and one N3+ atom. In the third O2- site, O2- is bonded in a 1-coordinate geometry to two K1+ and one N3+ atom. In the fourth O2- site, O2- is bonded in a 1-coordinate geometry to two equivalent K1+ and one N3+ atom. In the fifth O2- site, O2- is bonded in a distorted single-bond geometry to two K1+ and one N3+ atom. In the sixth O2- site, O2- is bonded in a 1-coordinate geometry to two equivalent K1+ and one N3+ atom. In the seventh O2- site, O2- is bonded in a distorted single-bond geometry to two K1+ and one N3+ atom. In the eighth O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent K1+ and one N3+ atom.

K2Pt(NO2)4 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional and consists of four platinum black molecules and one K(NO2)2 framework. In the K(NO2)2 framework, there are two inequivalent K1+ sites. In the first K1+ site, K1+ is bonded to eight O2- atoms to form distorted corner-sharing KO8 hexagonal bipyramids. There are a spread of K–O bond distances ranging from 2.77–3.30 Å. In the second K1+ site, K1+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of K–O bond distances ranging from 2.71–3.03 Å. There are four inequivalent N3+ sites. In the first N3+ site, N3+ is bonded in a bent 120 degrees geometry to two O2- atoms. There is one shorter (1.25 Å) and one longer (1.26 Å) N–O bond length. In the second N3+ site, N3+ is bonded in a bent 120 degrees geometry to two O2- atoms. Both N–O bond lengths are 1.25 Å. In the third N3+ site, N3+ is bonded in a bent 120 degrees geometry to two O2- atoms. Both N–O bond lengths are 1.25 Å.
