Materials Data on Si2Os by Materials Project
OsSi2 crystallizes in the orthorhombic Cmce space group. The structure is three-dimensional. there are two inequivalent Os8+ sites. In the first Os8+ site, Os8+ is bonded in a 8-coordinate geometry to eight Si4- atoms. There are a spread of Os–Si bond distances ranging from 2.48–2.53 Å. In the second Os8+ site, Os8+ is bonded in a 8-coordinate geometry to eight Si4- atoms. There are a spread of Os–Si bond distances ranging from 2.47–2.50 Å. There are two inequivalent Si4- sites. In the first Si4- site, Si4- is bonded in a 4-coordinate geometry to four Os8+ and five Si4- atoms. There are a spread of Si–Si bond distances ranging from 2.55–2.72 Å. In the second Si4- site, Si4- is bonded in a 4-coordinate geometry to four Os8+ and five Si4- atoms. There are one shorter (2.62 Å) and one longer (2.71 Å) Si–Si bond lengths.
