La2CoMnO6 is Orthorhombic Perovskite-derived structured and crystallizes in the monoclinic C2/m space group. La(1) is bonded in a 5-coordinate geometry to one O(2) and four equivalent O(1) atoms. Mn(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form MnO6 octahedra that share corners with six equivalent Co(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 20-26°. Co(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form CoO6 octahedra that share corners with six equivalent Mn(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 20-26°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to two equivalent La(1), one Mn(1), and one Co(1) atom. In the second O site, O(2) is bonded in a 3-coordinate geometry to one La(1), one Mn(1), and one Co(1) atom.
La2CoMnO6 is Orthorhombic Perovskite-derived structured and crystallizes in the monoclinic C2/m space group. La(1) is bonded in a 5-coordinate geometry to one O(2) and four equivalent O(1) atoms. The La(1)-O(2) bond length is 2.40 Å. There are two shorter (2.51 Å) and two longer (2.52 Å) La(1)-O(1) bond lengths. Mn(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form MnO6 octahedra that share corners with six equivalent Co(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 20-26°. Both Mn(1)-O(2) bond lengths are 1.95 Å. All Mn(1)-O(1) bond lengths are 1.94 Å. Co(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form CoO6 octahedra that share corners with six equivalent Mn(1)O6 octahedra.
