The material described by NdOsFeSi2 crystallizes in the tetragonal I-4m2 space group. Nd(1) is bonded in a 16-coordinate geometry to four equivalent Os(1), four equivalent Fe(1), and eight equivalent Si(1) atoms. Os(1) is bonded in a 4-coordinate geometry to four equivalent Nd(1), four equivalent Fe(1), and four equivalent Si(1) atoms. Fe(1) is bonded to four equivalent Nd(1), four equivalent Os(1), and four equivalent Si(1) atoms to form a mixture of distorted corner and face-sharing FeNd4Si4Os4 cuboctahedra. Si(1) is bonded in a 9-coordinate geometry to four equivalent Nd(1), two equivalent Os(1), two equivalent Fe(1), and one Si(1) atom. is represented by the CIF file [CIF]
