Na5Ni2P2(CO7)2 crystallizes in the monoclinic P2_1/m space group. The structure is three-dimensional. there are three inequivalent Na1+ sites. In the first Na1+ site, Na1+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Na–O bond distances ranging from 2.32–2.86 Å. In the second Na1+ site, Na1+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Na–O bond distances ranging from 2.29–2.79 Å. In the third Na1+ site, Na1+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Na–O bond distances ranging from 2.30–2.85 Å. There are two inequivalent Ni+2.50+ sites. In the first Ni+2.50+ site, Ni+2.50+ is bonded to six O2- atoms to form NiO6 octahedra that share corners with four equivalent PO4 tetrahedra. There are a spread of Ni–O bond distances ranging from 2.03–2.20 Å. In the second Ni+2.50+ site, Ni+2.50+ is bonded to six O2- atoms to form NiO6 octahedra that share corners with four equivalent PO4 tetrahedra. There are a spread of Ni–O bond distances ranging from 2.01–2.11 Å. There are two inequivalent C4+ sites. In the first C4+ site, C4+ is bonded in a trigonal planar geometry to three O2- atoms. There is one shorter (1.29 Å) and two longer (1.30 Å) C–O bond length. In the second C4+ site, C4+ is bonded in a trigonal planar geometry to three O2- atoms. There is one shorter (1.26 Å) and two longer (1.30 Å) C–O bond length. There are two inequivalent P5+ sites. In the first P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with four equivalent NiO6 octahedra. The corner-sharing octahedra tilt angles range from 39–50°. There are a spread of P–O bond distances ranging from 1.54–1.57 Å. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with four equivalent NiO6 octahedra. The corner-sharing octahedra tilt angles range from 37–48°. There are a spread of P–O bond distances ranging from 1.54–1.56 Å. There are twelve inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent Na1+ and one C4+ atom. In the second O2- site, O2- is bonded in a 1-coordinate geometry to three Na1+, one Ni+2.50+, and one C4+ atom. In the third O2- site, O2- is bonded in a 5-coordinate geometry to three Na1+, one Ni+2.50+, and one C4+ atom. In the fourth O2- site, O2- is bonded in a 1-coordinate geometry to two equivalent Na1+, one Ni+2.50+, and one P5+ atom. In the fifth O2- site, O2- is bonded in a distorted rectangular see-saw-like geometry to two equivalent Na1+, one Ni+2.50+, and one P5+ atom. In the sixth O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Na1+, one Ni+2.50+, and one P5+ atom. In the seventh O2- site, O2- is bonded in a 5-coordinate geometry to four Na1+ and one C4+ atom. In the eighth O2- site, O2- is bonded in a 1-coordinate geometry to two equivalent Na1+, one Ni+2.50+, and one C4+ atom. In the ninth O2- site, O2- is bonded in a distorted trigonal pyramidal geometry to two equivalent Na1+, one Ni+2.50+, and one C4+ atom. In the tenth O2- site, O2- is bonded in a 1-coordinate geometry to three Na1+, one Ni+2.50+, and one P5+ atom. In the eleventh O2- site, O2- is bonded in a distorted rectangular see-saw-like geometry to two equivalent Na1+, one Ni+2.50+, and one P5+ atom. In the twelfth O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Na1+, one Ni+2.50+, and one P5+ atom.
