The structure described by Ho5Co2Bi crystallizes in the tetragonal I4/mcm space group. There are two inequivalent Ho sites. In the first Ho site, Ho(1) is bonded to three equivalent Co(1) and two equivalent Bi(1) atoms to form a mixture of distorted face, corner, and edge-sharing HoCo3Bi2 square pyramids. In the second Ho site, Ho(2) is bonded in a 4-coordinate geometry to four equivalent Co(1) and two equivalent Bi(1) atoms. Co(1) is bonded in a 8-coordinate geometry to two equivalent Ho(2) and six equivalent Ho(1) atoms. Bi(1) is bonded in a 10-coordinate geometry to two equivalent Ho(2) and eight equivalent Ho(1) atoms. is represented by the CIF card [CIF]
