The material structure described by (NH3)2Si(NH3)2F4 is Indium-derived structured and crystallizes in the orthorhombic Cmce space group. The structure is zero-dimensional and consists of eight ammonia molecules and four Si(NH3)2F4 clusters. In each Si(NH3)2F4 cluster, Si(1) is bonded in an octahedral geometry to two equivalent N(1) and four equivalent F(1) atoms. N(1) is bonded to one Si(1), one H(2), and two equivalent H(1) atoms to form distorted corner-sharing NSiH3 tetrahedra. There are two 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. F(1) is bonded in a single-bond geometry to one Si(1) atom. is represented by the CIF card [CIF]
