Materials Data on MnNF3 by Materials Project

Abstract

(MnF3)2N2 is High-temperature superconductor-derived structured and crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional and consists of four ammonia molecules and one MnF3 framework. In the MnF3 framework, Mn2+ is bonded to six F1- atoms to form corner-sharing MnF6 octahedra. The corner-sharing octahedral tilt angles are 2°. There are a spread of Mn–F bond distances ranging from 1.89–2.14 Å. There are two inequivalent F1- sites. In the first F1- site, F1- is bonded in a linear geometry to two equivalent Mn2+ atoms. In the second F1- site, F1- is bonded in a linear geometry to two equivalent Mn2+ atoms.
