The compound described by OsSi3 is alpha bismuth trifluoride structured and crystallizes in the tetragonal I4/mmm space group. There are two inequivalent Os sites. In the first Os site, Os(1) is bonded in a distorted body-centered cubic geometry to six equivalent Si(2) and eight equivalent Si(1) atoms. In the second Os site, Os(1) is bonded in a distorted body-centered cubic geometry to six equivalent Si(2) and eight equivalent Si(1) atoms. There are two inequivalent Si sites. In the first Si site, Si(1) is bonded in a distorted body-centered cubic geometry to four Os(1,1) and four equivalent Si(2) atoms. In the second Si site, Si(2) is bonded in a 14-coordinate geometry to six Os(1,1) and eight equivalent Si(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
