The structure described by Nd3Os is Cementite structured and crystallizes in the orthorhombic Pnma space group. There are two inequivalent Nd sites. In the first Nd site, Nd(1) is bonded in a 3-coordinate geometry to three equivalent Os(1) atoms. In the second Nd site, Nd(2) is bonded in a distorted bent 150 degrees geometry to two equivalent Os(1) atoms. Os(1) is bonded in a 8-coordinate geometry to two equivalent Nd(2) and six equivalent Nd(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
