LaNiO3 is Orthorhombic Perovskite-like structured and crystallizes in the triclinic P-1 space group. La(1) is bonded in a 9-coordinate geometry to three equivalent O(2), three equivalent O(3), and four equivalent O(1) atoms. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form corner-sharing NiO6 octahedra. The corner-sharing octahedral tilt angles range from 20-23°. In the second Ni site, Ni(2) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form corner-sharing NiO6 octahedra. The corner-sharing octahedral tilt angles range from 20-23°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 6-coordinate geometry to four equivalent La(1), one Ni(1), and one Ni(2) atom. In the second O site, O(2) is bonded in a 3-coordinate geometry to three equivalent La(1), one Ni(1), and one Ni(2) atom. In the third O site, O(3) is bonded in a 5-coordinate geometry to three equivalent La(1), one Ni(1), and one Ni(2) atom.
