TmOs3 is Uranium Silicide-like structured and crystallizes in the hexagonal P6_3/mmc space group. Tm(1) is bonded to twelve equivalent Os(1) atoms to form a mixture of face and corner-sharing TmOs12 cuboctahedra. Os(1) is bonded in a distorted see-saw-like geometry to four equivalent Tm(1) atoms.
TmOs3 is Uranium Silicide-like structured and crystallizes in the hexagonal P6_3/mmc space group. Tm(1) is bonded to twelve equivalent Os(1) atoms to form a mixture of face and corner-sharing TmOs12 cuboctahedra. There are six shorter (2.87 Å) and six longer (2.89 Å) Tm(1)-Os(1) bond lengths. Os(1) is bonded in a distorted see-saw-like geometry to four equivalent Tm(1) atoms.
