Materials Data on Tm3Os by Materials Project

Tm3Os is Cementite structured and crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. there are two inequivalent Tm sites. In the first Tm site, Tm is bonded in a distorted bent 150 degrees geometry to two equivalent Os atoms. There are one shorter (2.73 Å) and one longer (2.79 Å) Tm–Os bond lengths. In the second Tm site, Tm is bonded in a 3-coordinate geometry to three equivalent Os atoms. There are a spread of Tm–Os bond distances ranging from 2.84–3.10 Å. Os is bonded in a 8-coordinate geometry to eight Tm atoms.

Materials Data on TmOs3 by Materials Project

TmOs3 is Uranium Silicide-like structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Tm3+ is bonded to twelve equivalent Os1- atoms to form a mixture of corner and face-sharing TmOs12 cuboctahedra. There are six shorter (2.87 Å) and six longer (2.89 Å) Tm–Os bond lengths. Os1- is bonded in a distorted see-saw-like geometry to four equivalent Tm3+ atoms.
