The structure described by (N2)3(SiF6)2F2 is Indium-derived structured and crystallizes in the tetragonal P4/mbm space group. The structure is zero-dimensional and consists of six ammonia atoms, two hydrofluoric acid atoms, and two SiF6 clusters. In each SiF6 cluster, Si(1) is bonded in an octahedral geometry to two equivalent F(1) and four equivalent F(2) atoms. There are two inequivalent F sites. In the first F site, F(1) is bonded in a single-bond geometry to one Si(1) atom. In the second F site, F(2) is bonded in a single-bond geometry to one Si(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
