The crystal structure described by LiEuO2 is Ilmenite-like structured and crystallizes in the orthorhombic Pnma space group. Li(1) is bonded to one O(2) and three equivalent O(1) atoms to form distorted LiO4 tetrahedra that share corners with six equivalent Eu(1)O6 octahedra, corners with two equivalent Li(1)O4 tetrahedra, edges with three equivalent Eu(1)O6 octahedra, and edges with two equivalent Li(1)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 6-73°. Eu(1) is bonded to three equivalent O(1) and three equivalent O(2) atoms to form EuO6 octahedra that share corners with four equivalent Eu(1)O6 octahedra, corners with six equivalent Li(1)O4 tetrahedra, edges with four equivalent Eu(1)O6 octahedra, and edges with three equivalent Li(1)O4 tetrahedra. The corner-sharing octahedral tilt angles are 54°. There are two inequivalent O sites. In the first O site, O(1) is bonded to three equivalent Li(1) and three equivalent Eu(1) atoms to form distorted OLi3Eu3 octahedra that share corners with six equivalent O(2)LiEu3 trigonal pyramids, edges with six equivalent O(1)Li3Eu3 octahedra, and edges with three equivalent O(2)LiEu3 trigonal pyramids. In the second O site, O(2) is bonded to one Li(1) and three equivalent Eu(1) atoms to form distorted OLiEu3 trigonal pyramids that share corners with six equivalent O(1)Li3Eu3 octahedra, corners with six equivalent O(2)LiEu3 trigonal pyramids, and edges with three equivalent O(1)Li3Eu3 octahedra. The corner-sharing octahedral tilt angles range from 3-81°. is represented by the CIF card [CIF]
