Materials Data on TeAsOs by Materials Project
OsAsTe crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Os5+ is bonded to three equivalent As3- and three equivalent Te2- atoms to form OsTe3As3 octahedra that share corners with eight equivalent OsTe3As3 octahedra, corners with three equivalent AsTeOs3 tetrahedra, corners with three equivalent TeAsOs3 tetrahedra, and edges with two equivalent OsTe3As3 octahedra. The corner-sharing octahedra tilt angles range from 54–58°. All Os–As bond lengths are 2.55 Å. There are two shorter (2.61 Å) and one longer (2.62 Å) Os–Te bond lengths. As3- is bonded to three equivalent Os5+ and one Te2- atom to form distorted AsTeOs3 tetrahedra that share corners with three equivalent OsTe3As3 octahedra, corners with four equivalent AsTeOs3 tetrahedra, corners with nine equivalent TeAsOs3 tetrahedra, and an edgeedge with one AsTeOs3 tetrahedra. The corner-sharing octahedra tilt angles range from 65–74°. The As–Te bond length is 2.74 Å. Te2- is bonded to three equivalent Os5+ and one As3- atom to form distorted TeAsOs3 tetrahedra that share corners with three equivalent OsTe3As3 octahedra, corners with four equivalent TeAsOs3 tetrahedra, corners with nine equivalent AsTeOs3 tetrahedra, and an edgeedge with one TeAsOs3 tetrahedra. The corner-sharing octahedra tilt angles range from 74–82°.
