Materials Data on Ho5Co2Bi by Materials Project
Ho5Co2Bi crystallizes in the tetragonal I4/mcm space group. The structure is three-dimensional. there are two inequivalent Ho sites. In the first Ho site, Ho is bonded to three equivalent Co and two equivalent Bi atoms to form a mixture of distorted edge, face, and corner-sharing HoCo3Bi2 square pyramids. There are one shorter (2.83 Å) and two longer (2.86 Å) Ho–Co bond lengths. Both Ho–Bi bond lengths are 3.32 Å. In the second Ho site, Ho is bonded in a 4-coordinate geometry to four equivalent Co and two equivalent Bi atoms. All Ho–Co bond lengths are 2.93 Å. Both Ho–Bi bond lengths are 3.55 Å. Co is bonded in a 8-coordinate geometry to eight Ho atoms. Bi is bonded in a 10-coordinate geometry to ten Ho atoms.
