GdNiO3 is Orthorhombic Perovskite structured and crystallizes in the orthorhombic Pnma space group. Gd(1) is bonded in a 8-coordinate geometry to two equivalent O(1) and six equivalent O(2) atoms. Ni(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form corner-sharing NiO6 octahedra. The corner-sharing octahedral tilt angles range from 29-30°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to two equivalent Gd(1) and two equivalent Ni(1) atoms. In the second O site, O(2) is bonded in a 5-coordinate geometry to three equivalent Gd(1) and two equivalent Ni(1) atoms.
GdNiO3 is Orthorhombic Perovskite structured and crystallizes in the orthorhombic Pnma space group. Gd(1) is bonded in a 8-coordinate geometry to two equivalent O(1) and six equivalent O(2) atoms. There is one shorter (2.29 Å) and one longer (2.34 Å) Gd(1)-O(1) bond length. There are a spread of Gd(1)-O(2) bond distances ranging from 2.33-2.59 Å. Ni(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form corner-sharing NiO6 octahedra. The corner-sharing octahedral tilt angles range from 29-30°. Both Ni(1)-O(1) bond lengths are 1.93 Å. There are two shorter (1.95 Å) and two longer (1.98 Å) Ni(1)-O(2) bond lengths. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to two equivalent Gd(1) and two equivalent Ni(1) atoms. In the second O site, O(2) is bonded in a 5-coordinate geometry to three equivalent Gd(1) and two equivalent Ni(1) atoms.
