Materials Data on SrIn4Ir by Materials Project
SrIrIn4 crystallizes in the orthorhombic Pmma space group. The structure is three-dimensional. Sr is bonded in a 1-coordinate geometry to one Ir and twelve In atoms. The Sr–Ir bond length is 3.23 Å. There are a spread of Sr–In bond distances ranging from 3.43–3.77 Å. Ir is bonded in a 9-coordinate geometry to one Sr and eight In atoms. There are a spread of Ir–In bond distances ranging from 2.63–2.92 Å. There are three inequivalent In sites. In the first In site, In is bonded in a 2-coordinate geometry to four equivalent Sr, two equivalent Ir, and six In atoms. There are a spread of In–In bond distances ranging from 3.20–3.40 Å. In the second In site, In is bonded in a distorted rectangular see-saw-like geometry to two equivalent Sr, two equivalent Ir, and four equivalent In atoms. In the third In site, In is bonded in a linear geometry to two equivalent Sr, two equivalent Ir, and four equivalent In atoms.
