Materials Data on Sn7Ir2Os by Materials Project
OsIr2Sn7 crystallizes in the orthorhombic Fmm2 space group. The structure is three-dimensional. Os is bonded in a 8-coordinate geometry to eight Sn atoms. There are six shorter (2.78 Å) and two longer (2.79 Å) Os–Sn bond lengths. There are two inequivalent Ir sites. In the first Ir site, Ir is bonded in a 8-coordinate geometry to eight Sn atoms. There are a spread of Ir–Sn bond distances ranging from 2.79–2.81 Å. In the second Ir site, Ir is bonded in a 8-coordinate geometry to eight Sn atoms. There are a spread of Ir–Sn bond distances ranging from 2.78–2.83 Å. There are six inequivalent Sn sites. In the first Sn site, Sn is bonded in a 4-coordinate geometry to two equivalent Os, one Ir, and four Sn atoms. There are a spread of Sn–Sn bond distances ranging from 2.85–3.10 Å. In the second Sn site, Sn is bonded in a 4-coordinate geometry to three Ir and four Sn atoms. All Sn–Sn bond lengths are 3.12 Å. In the third Sn site, Sn is bonded in a 4-coordinate geometry to one Os, two Ir, and four Sn atoms. There are one shorter (2.85 Å) and one longer (3.10 Å) Sn–Sn bond lengths. In the fourth Sn site, Sn is bonded in a 8-coordinate geometry to one Os and three Ir atoms. In the fifth Sn site, Sn is bonded in a 8-coordinate geometry to one Os and three Ir atoms. In the sixth Sn site, Sn is bonded in a 8-coordinate geometry to two equivalent Os and two equivalent Ir atoms.
