Materials Data on Al6GeW by Materials Project

Abstract

WAl6Ge crystallizes in the cubic Pm-3 space group. The structure is three-dimensional. W is bonded to twelve equivalent Al atoms to form WAl12 cuboctahedra that share edges with six equivalent WAl12 cuboctahedra and faces with eight equivalent GeAl12 cuboctahedra. All W–Al bond lengths are 2.80 Å. Al is bonded in a 6-coordinate geometry to two equivalent W, two equivalent Al, and two equivalent Ge atoms. There are one shorter (2.47 Å) and one longer (2.56 Å) Al–Al bond lengths. Both Al–Ge bond lengths are 2.82 Å. Ge is bonded to twelve equivalent Al atoms to form GeAl12 cuboctahedra that share edges with six equivalent GeAl12 cuboctahedra and faces with eight equivalent WAl12 cuboctahedra.
