Sr2Cu(OF)2 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Sr2+ is bonded in a body-centered cubic geometry to four equivalent O2- and four equivalent F1- atoms. All Sr–O bond lengths are 2.66 Å. All Sr–F bond lengths are 2.50 Å. Cu2+ is bonded in a square co-planar geometry to four equivalent O2- atoms. All Cu–O bond lengths are 2.00 Å. O2- is bonded to four equivalent Sr2+ and two equivalent Cu2+ atoms to form distorted OSr4Cu2 octahedra that share corners with two equivalent OSr4Cu2 octahedra, corners with twelve equivalent FSr4 tetrahedra, edges with two equivalent OSr4Cu2 octahedra, edges with two equivalent FSr4 tetrahedra, and faces with four equivalent OSr4Cu2 octahedra. The corner-sharing octahedral tilt angles are 0°. F1- is bonded to four equivalent Sr2+ atoms to form FSr4 tetrahedra that share corners with twelve equivalent OSr4Cu2 octahedra, corners with four equivalent FSr4 tetrahedra, edges with two equivalent OSr4Cu2 octahedra, and edges with four equivalent FSr4 tetrahedra. The corner-sharing octahedra tilt angles range from 4–67°.
