Materials Data on GeH12(NF2)4 by Materials Project
(NH)2(NH4)2GeH2F8 crystallizes in the orthorhombic Pccn space group. The structure is zero-dimensional and consists of eight ammonia molecules, eight ammonium molecules, and four GeH2F8 clusters. In each GeH2F8 cluster, Ge4+ is bonded in an octahedral geometry to six F1- atoms. There are a spread of Ge–F bond distances ranging from 1.80–1.91 Å. H1+ is bonded in a linear geometry to two F1- atoms. There is one shorter (0.99 Å) and one longer (1.46 Å) H–F bond length. There are four inequivalent F1- sites. In the first F1- site, F1- is bonded in a single-bond geometry to one Ge4+ atom. In the second F1- site, F1- is bonded in a single-bond geometry to one Ge4+ atom. In the third F1- site, F1- is bonded in a bent 120 degrees geometry to one Ge4+ and one H1+ atom. In the fourth F1- site, F1- is bonded in a single-bond geometry to one H1+ atom.
