Materials Data on GaAu(I4N)2 by Materials Project
AuI4GaI4N2 is High Pressure (4-7GPa) Tellurium-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 GaI4 clusters. In each AuI4 cluster, Au3+ is bonded in a square co-planar geometry to four I1- atoms. There are two shorter (2.66 Å) and two longer (2.67 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 GaI4 cluster, Ga3+ is bonded in a tetrahedral geometry to four I1- atoms. There are two shorter (2.58 Å) and two longer (2.60 Å) Ga–I bond lengths. There are three inequivalent I1- sites. In the first I1- site, I1- is bonded in a single-bond geometry to one Ga3+ atom. In the second I1- site, I1- is bonded in a single-bond geometry to one Ga3+ atom. In the third I1- site, I1- is bonded in a single-bond geometry to one Ga3+ atom.
