NH4SiNH3F5 is lead oxide structured and crystallizes in the monoclinic Pc space group. The structure is zero-dimensional and consists of two ammonium molecules and two SiNH3F5 clusters. In each SiNH3F5 cluster, Si(1) is bonded in an octahedral geometry to one N(2), one F(1), one F(2), one F(3), one F(4), and one F(5) atom. N(2) is bonded in a distorted trigonal non-coplanar geometry to one Si(1), one H(5), one H(6), and one H(7) atom. There are three inequivalent H sites. In the first H site, H(5) is bonded in a single-bond geometry to one N(2) atom. In the second H site, H(6) is bonded in a single-bond geometry to one N(2) atom. In the third H site, H(7) is bonded in a single-bond geometry to one N(2) atom. There are five 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. In the third F site, F(3) is bonded in a single-bond geometry to one Si(1) atom. In the fourth F site, F(4) is bonded in a single-bond geometry to one Si(1) atom. In the fifth F site, F(5) is bonded in a single-bond geometry to one Si(1) atom.
