YOs3 is beta Cu3Ti-like structured and crystallizes in the hexagonal P6_3/mmc space group. Y(1) is bonded to twelve equivalent Os(1) atoms to form a mixture of corner and face-sharing YOs12 cuboctahedra. Os(1) is bonded in a distorted see-saw-like geometry to four equivalent Y(1) atoms.
YOs3 is beta Cu3Ti-like structured and crystallizes in the hexagonal P6_3/mmc space group. Y(1) is bonded to twelve equivalent Os(1) atoms to form a mixture of corner and face-sharing YOs12 cuboctahedra. There are six shorter (2.92 Å) and six longer (2.93 Å) Y(1)-Os(1) bond lengths. Os(1) is bonded in a distorted see-saw-like geometry to four equivalent Y(1) atoms.
