Ho3Bi is Uranium Silicide structured and crystallizes in the trigonal R3m space group. Ho(1) is bonded in a 1-coordinate geometry to four equivalent Bi(1) atoms. There are a spread of Ho(1)-Bi(1) bond distances ranging from 2.92-3.94 Å. Bi(1) is bonded to twelve equivalent Ho(1) atoms to form a mixture of distorted face and corner-sharing BiHo12 cuboctahedra.
