The structure described by La(OsSi)2 crystallizes in the tetragonal I4/mmm space group. La(1) is bonded in a 16-coordinate geometry to eight equivalent Os(1) and eight equivalent Si(1) atoms. Os(1) is bonded in a 4-coordinate geometry to four equivalent La(1) and four equivalent Si(1) atoms. Si(1) is bonded in a 4-coordinate geometry to four equivalent La(1) and four equivalent Os(1) atoms. is represented by the CIF file [CIF]
