Materials Data on Tc3Ru by Materials Project

Abstract

Tc3Ru is beta Cu3Ti-like structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. there are two inequivalent Tc+1.67- sites. In the first Tc+1.67- site, Tc+1.67- is bonded to eight equivalent Tc+1.67- and four equivalent Ru5+ atoms to form distorted TcTc8Ru4 cuboctahedra that share corners with four equivalent RuTc12 cuboctahedra, corners with fourteen equivalent TcTc8Ru4 cuboctahedra, edges with six equivalent RuTc12 cuboctahedra, edges with twelve equivalent TcTc8Ru4 cuboctahedra, faces with four equivalent RuTc12 cuboctahedra, and faces with sixteen TcTc8Ru4 cuboctahedra. There are a spread of Tc–Tc bond distances ranging from 2.69–2.79 Å. There are two shorter (2.71 Å) and two longer (2.76 Å) Tc–Ru bond lengths. In the second Tc+1.67- site, Tc+1.67- is bonded to eight equivalent Tc+1.67- and four equivalent Ru5+ atoms to form distorted TcTc8Ru4 cuboctahedra that share corners with four equivalent RuTc12 cuboctahedra, corners with fourteen TcTc8Ru4 cuboctahedra, edges with six equivalent RuTc12 cuboctahedra, edges with twelve equivalent TcTc8Ru4 cuboctahedra, faces with four equivalent RuTc12 cuboctahedra, and faces with sixteen TcTc8Ru4 cuboctahedra. There are a spread of Tc–Tc bond distances ranging from 2.69–2.79 Å. There are two shorter (2.71 Å) and two longer (2.76 Å) Tc–Ru bond lengths. Ru5+ is bonded to twelve Tc+1.67- atoms to form RuTc12 cuboctahedra that share corners with six equivalent RuTc12 cuboctahedra, corners with twelve TcTc8Ru4 cuboctahedra, edges with eighteen TcTc8Ru4 cuboctahedra, faces with eight equivalent RuTc12 cuboctahedra, and faces with twelve TcTc8Ru4 cuboctahedra.
