Materials Data on HoIn5Co by Materials Project
HoCoIn5 crystallizes in the tetragonal P4/mmm space group. The structure is three-dimensional. Ho is bonded to twelve In atoms to form HoIn12 cuboctahedra that share corners with four equivalent HoIn12 cuboctahedra, faces with four equivalent HoIn12 cuboctahedra, and faces with four equivalent InHo4In8 cuboctahedra. There are four shorter (3.24 Å) and eight longer (3.25 Å) Ho–In bond lengths. Co is bonded in a body-centered cubic geometry to eight equivalent In atoms. All Co–In bond lengths are 2.72 Å. There are two inequivalent In sites. In the first In site, In is bonded in a 4-coordinate geometry to two equivalent Ho, two equivalent Co, and seven In atoms. There are a spread of In–In bond distances ranging from 2.92–3.25 Å. In the second In site, In is bonded to four equivalent Ho and eight equivalent In atoms to form distorted InHo4In8 cuboctahedra that share corners with four equivalent InHo4In8 cuboctahedra, faces with four equivalent HoIn12 cuboctahedra, and faces with four equivalent InHo4In8 cuboctahedra.
