LiNiPO4 crystallizes in the orthorhombic Fdd2 space group. Li(1) is bonded in a 6-coordinate geometry to two equivalent O(2) and four equivalent O(1) atoms. Ni(1) is bonded in a 6-coordinate geometry to two equivalent O(1) and four equivalent O(2) atoms. P(1) is bonded in a tetrahedral geometry to two equivalent O(1) and two equivalent O(2) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to two equivalent Li(1), one Ni(1), and one P(1) atom. In the second O site, O(2) is bonded in a 4-coordinate geometry to one Li(1), two equivalent Ni(1), and one P(1) atom.
LiNiPO4 crystallizes in the orthorhombic Fdd2 space group. Li(1) is bonded in a 6-coordinate geometry to two equivalent O(2) and four equivalent O(1) atoms. Both Li(1)-O(2) bond lengths are 2.34 Å. There are two shorter (2.07 Å) and two longer (2.34 Å) Li(1)-O(1) bond lengths. Ni(1) is bonded in a 6-coordinate geometry to two equivalent O(1) and four equivalent O(2) atoms. Both Ni(1)-O(1) bond lengths are 2.15 Å. There are two shorter (2.01 Å) and two longer (2.29 Å) Ni(1)-O(2) bond lengths. P(1) is bonded in a tetrahedral geometry to two equivalent O(1) and two equivalent O(2) atoms. Both P(1)-O(1) bond lengths are 1.55 Å. Both P(1)-O(2) bond lengths are 1.56 Å. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to two equivalent Li(1), one Ni(1), and one P(1) atom. In the second O site, O(2) is bonded in a 4-coordinate geometry to one Li(1), two equivalent Ni(1), and one P(1) atom.
