Materials Data on BiAs2Os by Materials Project
OsBiAs2 crystallizes in the cubic F-43m space group. The structure is three-dimensional. Os3+ is bonded to four equivalent As3- atoms to form corner-sharing OsAs4 tetrahedra. All Os–As bond lengths are 2.94 Å. Bi3+ is bonded to four equivalent As3- atoms to form corner-sharing BiAs4 tetrahedra. All Bi–As bond lengths are 2.94 Å. There are two inequivalent As3- sites. In the first As3- site, As3- is bonded in a distorted body-centered cubic geometry to four equivalent Os3+ and four equivalent As3- atoms. All As–As bond lengths are 2.94 Å. In the second As3- site, As3- is bonded in a distorted body-centered cubic geometry to four equivalent Bi3+ and four equivalent As3- atoms.
