Materials Data on MnN2F5 by Materials Project
(MnF3)2N2(NF2)2 crystallizes in the orthorhombic Pnma space group. The structure is one-dimensional and consists of four ammonia molecules; four difluoroamine molecules; and two MnF3 ribbons oriented in the (0, 1, 0) direction. In each MnF3 ribbon, Mn3+ is bonded in a distorted square co-planar geometry to four F1- atoms. There is two shorter (1.80 Å) and two longer (1.93 Å) Mn–F bond length. There are two inequivalent F1- sites. In the first F1- site, F1- is bonded in a single-bond geometry to one Mn3+ atom. In the second F1- site, F1- is bonded in a bent 150 degrees geometry to two equivalent Mn3+ atoms.
