Materials Data on SbTeRu by Materials Project

RuSbTe is Pyrite-derived structured and crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Ru5+ is bonded to three equivalent Sb3- and three equivalent Te2- atoms to form RuSb3Te3 octahedra that share corners with eight equivalent RuSb3Te3 octahedra, corners with three equivalent TeSbRu3 tetrahedra, and edges with two equivalent RuSb3Te3 octahedra. The corner-sharing octahedra tilt angles range from 51–58°. There are one shorter (2.69 Å) and two longer (2.71 Å) Ru–Sb bond lengths. There are two shorter (2.61 Å) and one longer (2.62 Å) Ru–Te bond lengths. Sb3- is bonded in a 4-coordinate geometry to three equivalent Ru5+ and one Te2- atom. The Sb–Te bond length is 2.93 Å. Te2- is bonded to three equivalent Ru5+ and one Sb3- atom to form distorted TeSbRu3 tetrahedra that share corners with three equivalent RuSb3Te3 octahedra, corners with four equivalent TeSbRu3 tetrahedra, and an edgeedge with one TeSbRu3 tetrahedra. The corner-sharing octahedra tilt angles range from 76–80°.

Materials Data on Sb2TeRu by Materials Project

RuSb2Te is Skutterudite-derived structured and crystallizes in the orthorhombic Immm space group. The structure is three-dimensional. Ru2+ is bonded to four Sb and two equivalent Te2- atoms to form corner-sharing RuSb4Te2 octahedra. The corner-sharing octahedra tilt angles range from 51–56°. There are two shorter (2.66 Å) and two longer (2.67 Å) Ru–Sb bond lengths. Both Ru–Te bond lengths are 2.58 Å. There are two inequivalent Sb sites. In the first Sb site, Sb is bonded in a 2-coordinate geometry to two equivalent Ru2+ atoms. In the second Sb site, Sb is bonded in a 2-coordinate geometry to two equivalent Ru2+ and two equivalent Sb atoms. There are one shorter (2.88 Å) and one longer (2.99 Å) Sb–Sb bond lengths. Te2- is bonded in a 2-coordinate geometry to two equivalent Ru2+ atoms.
