Materials Data on Na3Co(NO2)6 by Materials Project

Na3Co(NO2)6 crystallizes in the trigonal R-3 space group. The structure is three-dimensional and consists of three cobalt molecules and one Na(NO2)2 framework. In the Na(NO2)2 framework, there are two inequivalent Na1+ sites. In the first Na1+ site, Na1+ is bonded to twelve O2- atoms to form a mixture of corner and face-sharing NaO12 cuboctahedra. The corner-sharing octahedral tilt angles are 48°. There are six shorter (2.71 Å) and six longer (2.92 Å) Na–O bond lengths. In the second Na1+ site, Na1+ is bonded to six O2- atoms to form a mixture of corner and face-sharing NaO6 octahedra. There are three shorter (2.35 Å) and three longer (2.37 Å) Na–O bond lengths. N3+ is bonded in a bent 120 degrees geometry to two O2- atoms. There is one shorter (1.24 Å) and one longer (1.25 Å) N–O bond length. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a 2-coordinate geometry to two Na1+ and one N3+ atom. In the second O2- site, O2- is bonded in a 3-coordinate geometry to two Na1+ and one N3+ atom.
