Materials Data on InI4N by Materials Project
(InI4)2N2 is Iron carbide-derived structured and crystallizes in the orthorhombic Pnna space group. The structure is zero-dimensional and consists of four ammonia molecules and four InI4 clusters. In each InI4 cluster, In3+ is bonded in a tetrahedral geometry to four I1- atoms. There are two shorter (2.76 Å) and two longer (2.79 Å) In–I bond lengths. There are two 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.
