The crystal structure described by Y3Os is Cementite structured and crystallizes in the orthorhombic Pnma space group. There are two inequivalent Y sites. In the first Y site, Y(1) is bonded in a 3-coordinate geometry to three equivalent Os(1) atoms. In the second Y site, Y(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 Y(2) and six equivalent Y(1) atoms. is represented by the CIF card [CIF]
