Be Al Cd Bi
BeCdAlBi crystallizes in the trigonal R3m space group. Be(1) is bonded in a distorted trigonal non-coplanar geometry to three equivalent Bi(1) atoms. All Be(1)-Bi(1) bond lengths are 2.96 Å. Cd(1) is bonded in a body-centered cubic geometry to four equivalent Al(1) and four equivalent Bi(1) atoms. There is one shorter (2.94 Å) and three longer (3.08 Å) Cd(1)-Al(1) bond lengths. There is one shorter (2.94 Å) and three longer (3.08 Å) Cd(1)-Bi(1) bond lengths. Al(1) is bonded to four equivalent Cd(1) atoms to form distorted corner-sharing AlCd4 tetrahedra. Bi(1) is bonded in a 7-coordinate geometry to three equivalent Be(1) and four equivalent Cd(1) atoms.
