Ni3P4(NO8)2 crystallizes in the monoclinic P2_1/c space group. The structure is two-dimensional and consists of one Ni3P4(NO8)2 sheet oriented in the (0, 0, 1) direction. there are two inequivalent Ni+3.33+ sites. In the first Ni+3.33+ site, Ni+3.33+ is bonded to six O2- atoms to form NiO6 octahedra that share corners with six PO4 tetrahedra and edges with two equivalent NiO6 octahedra. There are a spread of Ni–O bond distances ranging from 2.05–2.11 Å. In the second Ni+3.33+ site, Ni+3.33+ is bonded to six O2- atoms to form NiO6 octahedra that share corners with five PO4 tetrahedra and edges with two NiO6 octahedra. There are a spread of Ni–O bond distances ranging from 1.90–2.13 Å. 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 five NiO6 octahedra and a cornercorner with one PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 39–61°. There are a spread of P–O bond distances ranging from 1.51–1.63 Å. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with three NiO6 octahedra and a cornercorner with one PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 45–61°. There are a spread of P–O bond distances ranging from 1.50–1.62 Å. N1+ is bonded in a distorted single-bond geometry to one O2- atom. The N–O bond length is 1.43 Å. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 120 degrees geometry to two P5+ atoms. In the second O2- site, O2- is bonded in a water-like geometry to one P5+ and one N1+ atom. In the third O2- site, O2- is bonded in a single-bond geometry to one Ni+3.33+ atom. In the fourth O2- site, O2- is bonded in a bent 120 degrees geometry to one Ni+3.33+ and one P5+ atom. In the fifth O2- site, O2- is bonded in a 3-coordinate geometry to two Ni+3.33+ and one P5+ atom. In the sixth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Ni+3.33+ and one P5+ atom. In the seventh O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Ni+3.33+ and one P5+ atom. In the eighth O2- site, O2- is bonded in a 3-coordinate geometry to two Ni+3.33+ and one P5+ atom.
