Materials Data on GeN2F5 by Materials Project
N2(GeNF5)2 crystallizes in the tetragonal P4/n space group. The structure is two-dimensional and consists of two ammonia molecules and two GeNF5 sheets oriented in the (0, 0, 1) direction. In each GeNF5 sheet, Ge3+ is bonded in a distorted trigonal bipyramidal geometry to five F1- atoms. There is one shorter (1.74 Å) and four longer (1.80 Å) Ge–F bond length. N1+ is bonded in a rectangular see-saw-like geometry to four equivalent F1- atoms. All N–F bond lengths are 2.21 Å. There are two inequivalent F1- sites. In the first F1- site, F1- is bonded in a single-bond geometry to one Ge3+ and one N1+ atom. In the second F1- site, F1- is bonded in a single-bond geometry to one Ge3+ atom.
