Materials Data on HoBi3 by Materials Project
HoBi3 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Ho is bonded to twelve Bi atoms to form a mixture of edge, face, and corner-sharing HoBi12 cuboctahedra. There are four shorter (3.31 Å) and eight longer (3.61 Å) Ho–Bi bond lengths. There are two inequivalent Bi sites. In the first Bi site, Bi is bonded in a 12-coordinate geometry to four equivalent Ho and eight Bi atoms. There are four shorter (3.31 Å) and four longer (3.61 Å) Bi–Bi bond lengths. In the second Bi site, Bi is bonded in a square co-planar geometry to four equivalent Ho and eight equivalent Bi atoms.
