The crystal structure described by SrCaCrF7 crystallizes in the orthorhombic Pnma space group. Sr(1) is bonded in a 8-coordinate geometry to one F(2), one F(4), two equivalent F(1), two equivalent F(3), and two equivalent F(5) atoms. Ca(1) is bonded to one F(2), two equivalent F(3), two equivalent F(4), and two equivalent F(5) atoms to form CaF7 pentagonal bipyramids that share corners with three equivalent Cr(1)F6 octahedra, corners with two equivalent Ca(1)F7 pentagonal bipyramids, and  an edgeedge with one Cr(1)F6 octahedra. The corner-sharing octahedral tilt angles range from 33-50°. Cr(1) is bonded to one F(1), one F(2), two equivalent F(3), and two equivalent F(5) atoms to form CrF6 octahedra that share corners with three equivalent Ca(1)F7 pentagonal bipyramids and  an edgeedge with one Ca(1)F7 pentagonal bipyramid. There are five inequivalent F sites. In the first F site, F(5) is bonded in a 3-coordinate geometry to one Sr(1), one Ca(1), and one Cr(1) atom. In the second F site, F(1) is bonded in a distorted bent 150 degrees geometry to two equivalent Sr(1) and one Cr(1) atom. In the third F site, F(2) is bonded in a distorted trigonal planar geometry to one Sr(1), one Ca(1), and one Cr(1) atom. In the fourth F site, F(3) is bonded in a distorted trigonal planar geometry to one Sr(1), one Ca(1), and one Cr(1) atom. In the fifth F site, F(4) is bonded in a distorted trigonal planar geometry to one Sr(1) and two equivalent Ca(1) atoms. is represented by the CIF card [CIF]
