The crystal structure described by SrCrF6 crystallizes in the trigonal R-3m space group. Sr(1) is bonded to twelve equivalent F(1) atoms to form SrF12 cuboctahedra that share corners with six equivalent Cr(1)F6 octahedra, edges with six equivalent Sr(1)F12 cuboctahedra, and faces with two equivalent Cr(1)F6 octahedra. The corner-sharing octahedral tilt angles are 36°. Cr(1) is bonded to six equivalent F(1) atoms to form CrF6 octahedra that share corners with six equivalent Sr(1)F12 cuboctahedra and faces with two equivalent Sr(1)F12 cuboctahedra. F(1) is bonded in a distorted single-bond geometry to two equivalent Sr(1) and one Cr(1) atom. is represented by the CIF file [CIF]
