Materials Data on Mg5Bi by Materials Project
Abstract
Mg5Bi crystallizes in the monoclinic Cm space group. The structure is three-dimensional. there are five inequivalent Mg sites. In the first Mg site, Mg is bonded to ten Mg and two equivalent Bi atoms to form distorted MgMg10Bi2 cuboctahedra that share corners with two equivalent BiMg10 cuboctahedra, corners with twenty MgMg10Bi2 cuboctahedra, edges with four equivalent BiMg10 cuboctahedra, edges with ten MgMg7Bi3 cuboctahedra, faces with three equivalent BiMg10 cuboctahedra, and faces with seventeen MgMg10Bi2 cuboctahedra. There are a spread of Mg–Mg bond distances ranging from 3.19–3.34 Å. Both Mg–Bi bond lengths are 3.34 Å. In the second Mg site, Mg is bonded to seven Mg and three equivalent Bi atoms to form distorted MgMg7Bi3 cuboctahedra that share corners with twenty-two MgMg10Bi2 cuboctahedra, edges with four equivalent BiMg10 cuboctahedra, edges with ten MgMg10Bi2 cuboctahedra, a faceface with one BiMg10 cuboctahedra, and faces with fifteen MgMg10Bi2 cuboctahedra. There are a spread of Mg–Mg bond distances ranging from 3.25–3.31 Å. There are one shorter (3.18 Å) and two longer (3.26 Å) Mg–Bi bond lengths. In the third Mg site, Mg is bonded to ten Mg and two equivalent Bi atoms to form distorted MgMg10Bi2 cuboctahedra that share corners with eight equivalent BiMg10 cuboctahedra,more »
