EuOF is Fluorite-derived structured and crystallizes in the trigonal R-3m space group. Eu(1) is bonded in a body-centered cubic geometry to four equivalent O(1) and four equivalent F(1) atoms. O(1) is bonded to four equivalent Eu(1) atoms to form OEu4 tetrahedra that share corners with six equivalent O(1)Eu4 tetrahedra, corners with ten equivalent F(1)Eu4 tetrahedra, edges with three equivalent O(1)Eu4 tetrahedra, and edges with three equivalent F(1)Eu4 tetrahedra. F(1) is bonded to four equivalent Eu(1) atoms to form FEu4 tetrahedra that share corners with six equivalent F(1)Eu4 tetrahedra, corners with ten equivalent O(1)Eu4 tetrahedra, edges with three equivalent O(1)Eu4 tetrahedra, and edges with three equivalent F(1)Eu4 tetrahedra.
EuOF is Fluorite-derived structured and crystallizes in the trigonal R-3m space group. Eu(1) is bonded in a body-centered cubic geometry to four equivalent O(1) and four equivalent F(1) atoms. There is one shorter (2.31 Å) and three longer (2.34 Å) Eu(1)-O(1) bond lengths. There is one shorter (2.47 Å) and three longer (2.48 Å) Eu(1)-F(1) bond lengths. O(1) is bonded to four equivalent Eu(1) atoms to form OEu4 tetrahedra that share corners with six equivalent O(1)Eu4 tetrahedra, corners with ten equivalent F(1)Eu4 tetrahedra, edges with three equivalent O(1)Eu4 tetrahedra, and edges with three equivalent F(1)Eu4 tetrahedra.
