The compound described by Si(NH3)2F4 is alpha Po structured and crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of two Si(NH3)2F4 clusters. Si(1) is bonded in an octahedral geometry to two equivalent N(1), two equivalent F(1), and two equivalent F(2) atoms. N(1) is bonded in a distorted trigonal non-coplanar geometry to one Si(1), one H(1), one H(2), and one H(3) atom. There are three inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one N(1) atom. In the second H site, H(2) is bonded in a single-bond geometry to one N(1) atom. In the third H site, H(3) is bonded in a single-bond geometry to one N(1) atom. 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 CIF file [CIF]
