Materials Data on In by Materials Project

Abstract

In is alpha structured and crystallizes in the cubic I-43m space group. The structure is three-dimensional. there are four inequivalent In sites. In the first In site, In is bonded in a 4-coordinate geometry to four equivalent In atoms. All In–In bond lengths are 3.58 Å. In the second In site, In is bonded in a 3-coordinate geometry to ten In atoms. There are three shorter (3.31 Å) and six longer (3.54 Å) In–In bond lengths. In the third In site, In is bonded in a 10-coordinate geometry to ten In atoms. There are a spread of In–In bond distances ranging from 3.07–3.43 Å. In the fourth In site, In is bonded in a 12-coordinate geometry to twelve In atoms. There are two shorter (3.46 Å) and four longer (3.55 Å) In–In bond lengths.
