description: NiNa2C4N4H6O3 crystallizes in the triclinic P-1 space group. The structure is two-dimensional and consists of four nickel molecules and one Na2C4N4H6O3 sheet oriented in the (1, 0, 0) direction. In the Na2C4N4H6O3 sheet, there are five inequivalent Na1+ sites. In the first Na1+ site, Na1+ is bonded to two N3- and four O2- atoms to form edge-sharing NaN2O4 octahedra. There are one shorter (2.45 Å) and one longer (2.50 Å) Na–N bond lengths. There are a spread of Na–O bond distances ranging from 2.39–2.50 Å. In the second Na1+ site, Na1+ is bonded to two N3- and four O2- atoms to form edge-sharing NaN2O4 octahedra. There are one shorter (2.47 Å) and one longer (2.50 Å) Na–N bond lengths. There are a spread of Na–O bond distances ranging from 2.38–2.50 Å. In the third Na1+ site, Na1+ is bonded to four N3- and two O2- atoms to form edge-sharing NaN4O2 octahedra. There are a spread of Na–N bond distances ranging from 2.47–2.58 Å.
