La2CoO4 is Orthorhombic Perovskite-like structured and crystallizes in the orthorhombic Cmce space group. La(1) is bonded in a 8-coordinate geometry to four equivalent O(1) and four equivalent O(2) atoms. Co(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form corner-sharing CoO6 octahedra. The corner-sharing octahedral tilt angles are 14°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 5-coordinate geometry to four equivalent La(1) and one Co(1) atom. In the second O site, O(2) is bonded to four equivalent La(1) and two equivalent Co(1) atoms to form a mixture of distorted face, corner, and edge-sharing OLa4Co2 octahedra. The corner-sharing octahedra are not tilted.
La2CoO4 is Orthorhombic Perovskite-like structured and crystallizes in the orthorhombic Cmce space group. La(1) is bonded in a 8-coordinate geometry to four equivalent O(1) and four equivalent O(2) atoms. There are a spread of La(1)-O(1) bond distances ranging from 2.32-2.82 Å. There are two shorter (2.54 Å) and two longer (2.75 Å) La(1)-O(2) bond lengths. Co(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form corner-sharing CoO6 octahedra. The corner-sharing octahedral tilt angles are 14°. Both Co(1)-O(1) bond lengths are 2.32 Å. All Co(1)-O(2) bond lengths are 2.00 Å. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 5-coordinate geometry to four equivalent La(1) and one Co(1) atom. In the second O site, O(2) is bonded to four equivalent La(1) and two equivalent Co(1) atoms to form a mixture of distorted face, corner, and edge-sharing OLa4Co2 octahedra. The corner-sharing octahedra are not tilted.
