Materials Data on Al3Zn by Materials Project
Al3Zn is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Zn is bonded to twelve equivalent Al atoms to form ZnAl12 cuboctahedra that share corners with twelve equivalent ZnAl12 cuboctahedra, edges with twenty-four equivalent AlAl8Zn4 cuboctahedra, faces with six equivalent ZnAl12 cuboctahedra, and faces with twelve equivalent AlAl8Zn4 cuboctahedra. All Zn–Al bond lengths are 2.84 Å. Al is bonded to four equivalent Zn and eight equivalent Al atoms to form AlAl8Zn4 cuboctahedra that share corners with twelve equivalent AlAl8Zn4 cuboctahedra, edges with eight equivalent ZnAl12 cuboctahedra, edges with sixteen equivalent AlAl8Zn4 cuboctahedra, faces with four equivalent ZnAl12 cuboctahedra, and faces with fourteen equivalent AlAl8Zn4 cuboctahedra. All Al–Al bond lengths are 2.84 Å.
