Materials Data on BaMg6Ti by Materials Project
Abstract
BaMg6Ti crystallizes in the orthorhombic Amm2 space group. The structure is three-dimensional. Ba is bonded to ten Mg and two equivalent Ti atoms to form BaMg10Ti2 cuboctahedra that share corners with four equivalent MgBa2Mg10 cuboctahedra, corners with six equivalent BaMg10Ti2 cuboctahedra, edges with two equivalent MgBa2Mg10 cuboctahedra, edges with four equivalent TiBa2Mg10 cuboctahedra, faces with two equivalent BaMg10Ti2 cuboctahedra, faces with two equivalent TiBa2Mg10 cuboctahedra, and faces with eight MgMg10Ti2 cuboctahedra. There are a spread of Ba–Mg bond distances ranging from 3.26–3.45 Å. Both Ba–Ti bond lengths are 3.35 Å. There are four inequivalent Mg sites. In the first Mg site, Mg is bonded in a 12-coordinate geometry to two equivalent Ba, six Mg, and two equivalent Ti atoms. There are a spread of Mg–Mg bond distances ranging from 3.24–3.39 Å. There are one shorter (3.12 Å) and one longer (3.59 Å) Mg–Ti bond lengths. In the second Mg site, Mg is bonded to ten Mg and two equivalent Ti atoms to form distorted MgMg10Ti2 cuboctahedra that share corners with four equivalent TiBa2Mg10 cuboctahedra, corners with six equivalent MgMg10Ti2 cuboctahedra, edges with two equivalent TiBa2Mg10 cuboctahedra, edges with four equivalent MgBa2Mg10 cuboctahedra, faces with two equivalent TiBa2Mg10 cuboctahedra, faces withmore »
