The crystal structure described by NH4MnF3 is Orthorhombic Perovskite structured and crystallizes in the orthorhombic Pnma space group. The structure consists of four ammonium molecules inside a MnF3 framework. In the MnF3 framework, Mn(1) is bonded to two equivalent F(1) and four equivalent F(2) atoms to form corner-sharing MnF6 octahedra. The corner-sharing octahedral tilt angles range from 11-13°. There are two inequivalent F sites. In the first F site, F(1) is bonded in a linear geometry to two equivalent Mn(1) atoms. In the second F site, F(2) is bonded in a distorted linear geometry to two equivalent Mn(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
