Abstract
MgTi crystallizes in the orthorhombic Pmm2 space group. The structure is three-dimensional. there are three inequivalent Mg sites. In the first Mg site, Mg is bonded to six Mg and six Ti atoms to form distorted MgMg6Ti6 cuboctahedra that share corners with four equivalent TiMg6Ti6 cuboctahedra, corners with fourteen MgMg6Ti6 cuboctahedra, edges with six TiMg6Ti6 cuboctahedra, edges with eight MgMg6Ti6 cuboctahedra, faces with four TiMg6Ti6 cuboctahedra, and faces with eight MgMg6Ti6 cuboctahedra. There are a spread of Mg–Mg bond distances ranging from 2.91–3.30 Å. There are a spread of Mg–Ti bond distances ranging from 2.98–3.06 Å. In the second Mg site, Mg is bonded to six Mg and six Ti atoms to form distorted MgMg6Ti6 cuboctahedra that share corners with eight equivalent TiMg6Ti6 cuboctahedra, corners with ten MgMg6Ti6 cuboctahedra, edges with four equivalent TiMg6Ti6 cuboctahedra, edges with six MgMg6Ti6 cuboctahedra, faces with six TiMg6Ti6 cuboctahedra, and faces with ten MgMg6Ti6 cuboctahedra. Both Mg–Mg bond lengths are 3.07 Å. There are four shorter (3.07 Å) and two longer (3.11 Å) Mg–Ti bond lengths. In the third Mg site, Mg is bonded to six Mg and six Ti atoms to form MgMg6Ti6 cuboctahedra that share corners with two equivalent MgMg6Ti6 cuboctahedra, cornersmore »
