The crystal structure described by RbMnF4 crystallizes in the monoclinic P2_1/c space group. Rb(1) is bonded in a 10-coordinate geometry to two equivalent F(3), two equivalent F(4), three equivalent F(1), and three equivalent F(2) atoms. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded to two equivalent F(1), two equivalent F(3), and two equivalent F(4) atoms to form corner-sharing MnF6 octahedra. The corner-sharing octahedral tilt angles range from 28-33°. In the second Mn site, Mn(2) is bonded to two equivalent F(2), two equivalent F(3), and two equivalent F(4) atoms to form corner-sharing MnF6 octahedra. The corner-sharing octahedral tilt angles range from 28-33°. There are four inequivalent F sites. In the first F site, F(1) is bonded in a distorted single-bond geometry to three equivalent Rb(1) and one Mn(1) atom. In the second F site, F(2) is bonded in a distorted single-bond geometry to three equivalent Rb(1) and one Mn(2) atom. In the third F site, F(3) is bonded in a distorted bent 150 degrees geometry to two equivalent Rb(1), one Mn(1), and one Mn(2) atom. In the fourth F site, F(4) is bonded in a distorted bent 150 degrees geometry to two equivalent Rb(1), one Mn(1), and one Mn(2) atom. is represented by the CIF file [CIF]
