Materials Data on SbAsRu by Materials Project
RuSbAs crystallizes in the monoclinic P2/m space group. The structure is three-dimensional. there are two inequivalent Ru6+ sites. In the first Ru6+ site, Ru6+ is bonded to four equivalent Sb3- and two equivalent As3- atoms to form RuSb4As2 octahedra that share corners with eight equivalent RuSb2As4 octahedra, corners with two equivalent AsAsRu3 tetrahedra, and edges with two equivalent RuSb4As2 octahedra. The corner-sharing octahedra tilt angles range from 50–55°. All Ru–Sb bond lengths are 2.63 Å. Both Ru–As bond lengths are 2.55 Å. In the second Ru6+ site, Ru6+ is bonded to two equivalent Sb3- and four equivalent As3- atoms to form RuSb2As4 octahedra that share corners with eight equivalent RuSb4As2 octahedra, corners with four equivalent AsAsRu3 tetrahedra, and edges with two equivalent RuSb2As4 octahedra. The corner-sharing octahedra tilt angles range from 50–55°. Both Ru–Sb bond lengths are 2.59 Å. All Ru–As bond lengths are 2.56 Å. Sb3- is bonded in a 4-coordinate geometry to three Ru6+ and three equivalent Sb3- atoms. There are one shorter (2.79 Å) and two longer (3.13 Å) Sb–Sb bond lengths. As3- is bonded to three Ru6+ and one As3- atom to form distorted AsAsRu3 tetrahedra that share corners with three RuSb4As2 octahedra, corners with five equivalent AsAsRu3 tetrahedra, and an edgeedge with one AsAsRu3 tetrahedra. The corner-sharing octahedral tilt angles are 71°. The As–As bond length is 2.77 Å.
