The crystal structure described by NdOsSi3 crystallizes in the tetragonal I4mm space group. Nd(1) is bonded in a 17-coordinate geometry to five equivalent Os(1), four equivalent Si(1), and eight equivalent Si(2) atoms. Os(1) is bonded in a 5-coordinate geometry to five equivalent Nd(1), one Si(1), and four equivalent Si(2) atoms. There are two inequivalent Si sites. In the first Si site, Si(1) is bonded in a distorted single-bond geometry to four equivalent Nd(1), one Os(1), and four equivalent Si(2) atoms. In the second Si site, Si(2) is bonded in a distorted bent 120 degrees geometry to four equivalent Nd(1), two equivalent Os(1), and two equivalent Si(1) atoms. is represented by the CIF file [CIF]
