Abstract

Mg2Ti is beta-derived structured and crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. there are two inequivalent Mg sites. In the first Mg site, Mg is bonded to ten Mg and two equivalent Ti atoms to form distorted MgMg10Ti2 cuboctahedra that share corners with six equivalent TiMg8Ti4 cuboctahedra, corners with twelve MgMg10Ti2 cuboctahedra, edges with seven MgMg10Ti2 cuboctahedra, edges with eleven equivalent TiMg8Ti4 cuboctahedra, faces with four equivalent TiMg8Ti4 cuboctahedra, and faces with sixteen MgMg10Ti2 cuboctahedra. There are a spread of Mg–Mg bond distances ranging from 3.00–3.30 Å. Both Mg–Ti bond lengths are 3.17 Å. In the second Mg site, Mg is bonded to six Mg and six equivalent Ti atoms to form distorted MgMg6Ti6 cuboctahedra that share corners with six equivalent TiMg8Ti4 cuboctahedra, corners with twelve MgMg10Ti2 cuboctahedra, edges with seven equivalent TiMg8Ti4 cuboctahedra, edges with eleven MgMg6Ti6 cuboctahedra, faces with six equivalent TiMg8Ti4 cuboctahedra, and faces with fourteen MgMg6Ti6 cuboctahedra. Both Mg–Mg bond lengths are 3.02 Å. There are two shorter (2.97 Å) and four longer (3.07 Å) Mg–Ti bond lengths. Ti is bonded to eight Mg and four equivalent Ti atoms to form TiMg8Ti4 cuboctahedra that share corners with six equivalent TiMg8Ti4 cuboctahedra, cornersmore »« less
