RbCrF5 crystallizes in the orthorhombic Pmc2_1 space group. There are two inequivalent Rb sites. In the first Rb site, Rb(1) is bonded in a 11-coordinate geometry to one F(4), two equivalent F(1), two equivalent F(2), two equivalent F(6), and four equivalent F(3) atoms. In the second Rb site, Rb(2) is bonded in a 11-coordinate geometry to one F(7), two equivalent F(2), two equivalent F(3), two equivalent F(5), and four equivalent F(1) atoms. There are two inequivalent Cr sites. In the first Cr site, Cr(1) is bonded to one F(6), one F(7), two equivalent F(2), and two equivalent F(3) atoms to form corner-sharing CrF6 octahedra. The corner-sharing octahedral tilt angles are 33°. In the second Cr site, Cr(2) is bonded to one F(4), one F(5), two equivalent F(1), and two equivalent F(2) atoms to form corner-sharing CrF6 octahedra. The corner-sharing octahedral tilt angles are 33°. There are seven inequivalent F sites. In the first F site, F(1) is bonded in a distorted single-bond geometry to one Rb(1), two equivalent Rb(2), and one Cr(2) atom. In the second F site, F(2) is bonded in a bent 150 degrees geometry to one Rb(1), one Rb(2), one Cr(1), and one Cr(2) atom.
