SmF2 is Fluorite structured and crystallizes in the cubic Fm-3m space group. Sm(1) is bonded in a body-centered cubic geometry to eight equivalent F(1) atoms. F(1) is bonded to four equivalent Sm(1) atoms to form a mixture of corner and edge-sharing FSm4 tetrahedra.
SmF2 is Fluorite structured and crystallizes in the cubic Fm-3m space group. Sm(1) is bonded in a body-centered cubic geometry to eight equivalent F(1) atoms. All Sm(1)-F(1) bond lengths are 2.48 Å. F(1) is bonded to four equivalent Sm(1) atoms to form a mixture of corner and edge-sharing FSm4 tetrahedra.
