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.
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. There are a spread of Y(1)-Os(1) bond distances ranging from 2.86-3.16 Å. In the second Y site, Y(2) is bonded in a distorted bent 150 degrees geometry to two equivalent Os(1) atoms. There is one shorter (2.73 Å) and one longer (2.85 Å) Y(2)-Os(1) bond length. Os(1) is bonded in a 8-coordinate geometry to two equivalent Y(2) and six equivalent Y(1) atoms.
