NiBPO6 crystallizes in the trigonal P3_121 space group. The structure is three-dimensional. there are two inequivalent Ni4+ sites. In the first Ni4+ site, Ni4+ is bonded to six O2- atoms to form distorted NiO6 octahedra that share corners with two equivalent BO4 tetrahedra, corners with four equivalent PO4 tetrahedra, and edges with two equivalent NiO6 octahedra. There are a spread of Ni–O bond distances ranging from 1.97–2.13 Å. In the second Ni4+ site, Ni4+ is bonded to six O2- atoms to form NiO6 octahedra that share corners with two equivalent BO4 tetrahedra, corners with four equivalent PO4 tetrahedra, and edges with two equivalent NiO6 octahedra. There are a spread of Ni–O bond distances ranging from 2.01–2.12 Å. B3+ is bonded to four O2- atoms to form BO4 tetrahedra that share corners with two NiO6 octahedra and corners with two equivalent PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 29–48°. There are a spread of B–O bond distances ranging from 1.44–1.48 Å. P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with four NiO6 octahedra and corners with two equivalent BO4 tetrahedra. The corner-sharing octahedra tilt angles range from 42–60°. There are a spread of P–O bond distances ranging from 1.53–1.57 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to two Ni4+ and one P5+ atom. In the second O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Ni4+ and one B3+ atom. In the third O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one B3+ and one P5+ atom. In the fourth O2- site, O2- is bonded in a bent 150 degrees geometry to one Ni4+ and one B3+ atom. In the fifth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one B3+ and one P5+ atom. In the sixth O2- site, O2- is bonded in a 3-coordinate geometry to two Ni4+ and one P5+ atom.
