(NH4)2SiF6 is Silicon tetrafluoride-derived structured and crystallizes in the hexagonal P6_3mc space group. The structure is zero-dimensional and consists of four ammonium molecules and two SiF6 clusters. In each SiF6 cluster, Si(1) is bonded in an octahedral geometry to three equivalent F(1) and three 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.

The structure is zero-dimensional and consists of four ammonium molecules and two SiF6 clusters. In each SiF6 cluster, Si(1) is bonded in an octahedral geometry to three equivalent F(1) and three equivalent F(2) atoms. All Si(1)-F(1) bond lengths are 1.73 Å. All Si(1)-F(2) bond lengths are 1.72 Å. 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.
