The compound described by (NH4)3AlF6 is Silicon tetrafluoride-derived structured and crystallizes in the orthorhombic Aea2 space group. The structure is zero-dimensional and consists of twelve ammonium molecules and four AlF6 clusters. In each AlF6 cluster, Al(1) is bonded in an octahedral geometry to one F(1), one F(2), two equivalent F(3), and two equivalent F(4) atoms. There are four inequivalent F sites. In the first F site, F(1) is bonded in a single-bond geometry to one Al(1) atom. In the second F site, F(2) is bonded in a single-bond geometry to one Al(1) atom. In the third F site, F(3) is bonded in a single-bond geometry to one Al(1) atom. In the fourth F site, F(4) is bonded in a single-bond geometry to one Al(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
