The compound described by Sm3Os is Cementite structured and crystallizes in the orthorhombic Pnma space group. There are two inequivalent Sm sites. In the first Sm site, Sm(1) is bonded in a 3-coordinate geometry to three equivalent Os(1) atoms. In the second Sm site, Sm(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 Sm(2) and six equivalent Sm(1) atoms. is represented by the CIF file [CIF]
