Materials Data on InAu(I4N)2 by Materials Project
AuI4InI4N2 is Modderite-derived structured and crystallizes in the orthorhombic Pnma space group. The structure is zero-dimensional and consists of eight ammonia molecules, four AuI4 clusters, and four InI4 clusters. In each AuI4 cluster, Au3+ is bonded in a distorted rectangular see-saw-like geometry to four I1- atoms. There are two shorter (2.69 Å) and two longer (2.70 Å) Au–I bond lengths. There are two inequivalent I1- sites. In the first I1- site, I1- is bonded in a distorted single-bond geometry to one Au3+ atom. In the second I1- site, I1- is bonded in a distorted single-bond geometry to one Au3+ atom. In each InI4 cluster, In3+ is bonded in a tetrahedral geometry to four I1- atoms. There are a spread of In–I bond distances ranging from 2.71–2.83 Å. There are three inequivalent I1- sites. In the first I1- site, I1- is bonded in a single-bond geometry to one In3+ atom. In the second I1- site, I1- is bonded in a single-bond geometry to one In3+ atom. In the third I1- site, I1- is bonded in a single-bond geometry to one In3+ atom.
