There are a spread of P–O bond distances ranging from 1.52–1.58 Å. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with two NiO4 tetrahedra and corners with four LiO4 tetrahedra. There are a spread of P–O bond distances ranging from 1.52–1.57 Å. In the third P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with two NiO4 tetrahedra and corners with four LiO4 tetrahedra. There are a spread of P–O bond distances ranging from 1.53–1.57 Å. In the fourth P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with two NiO4 tetrahedra and corners with four LiO4 tetrahedra. There is two shorter (1.52 Å) and two longer (1.57 Å) P–O bond length. There are sixteen inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 120 degrees geometry to one Ni4+ and one P5+ atom. In the second O2- site, O2- is bonded in a bent 120 degrees geometry to one Ni4+ and one P5+ atom. In the third O2- site, O2- is bonded in a bent 120 degrees geometry to one Ni4+ and one P5+ atom. In the fourth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Ni4+ and one P5+ atom. In the fifth O2- site, O2- is bonded in a distorted trigonal planar geometry to two Li1+ and one P5+ atom. In the sixth O2- site, O2- is bonded in a distorted trigonal planar geometry to two Li1+ and one P5+ atom. In the seventh O2- site, O2- is bonded in a bent 120 degrees geometry to one Li1+ and one P5+ atom. In the eighth O2- site, O2- is bonded in a trigonal planar geometry to two Li1+ and one P5+ atom.
