Materials Data on KMnF3 by Materials Project
KMnF3 is (Cubic) Perovskite structured and crystallizes in the tetragonal I4/mcm space group. The structure is three-dimensional. K1+ is bonded to twelve F1- atoms to form KF12 cuboctahedra that share corners with twelve equivalent KF12 cuboctahedra, faces with six equivalent KF12 cuboctahedra, and faces with eight equivalent MnF6 octahedra. There are a spread of K–F bond distances ranging from 2.96–3.08 Å. Mn2+ is bonded to six F1- atoms to form MnF6 octahedra that share corners with six equivalent MnF6 octahedra and faces with eight equivalent KF12 cuboctahedra. The corner-sharing octahedra tilt angles range from 0–5°. All Mn–F bond lengths are 2.14 Å. There are two inequivalent F1- sites. In the first F1- site, F1- is bonded in a distorted linear geometry to four equivalent K1+ and two equivalent Mn2+ atoms. In the second F1- site, F1- is bonded in a distorted linear geometry to four equivalent K1+ and two equivalent Mn2+ atoms.
