Materials Data on Ho7In(CoGe3)4 by Materials Project
Ho7In(CoGe3)4 crystallizes in the tetragonal P4/m space group. The structure is three-dimensional. there are three inequivalent Ho sites. In the first Ho site, Ho is bonded in a 11-coordinate geometry to two equivalent Co, two equivalent In, and seven Ge atoms. Both Ho–Co bond lengths are 3.03 Å. Both Ho–In bond lengths are 3.32 Å. There are a spread of Ho–Ge bond distances ranging from 2.94–3.08 Å. In the second Ho site, Ho is bonded in a 8-coordinate geometry to four equivalent Co and twelve Ge atoms. All Ho–Co bond lengths are 3.14 Å. There are eight shorter (2.98 Å) and four longer (3.18 Å) Ho–Ge bond lengths. In the third Ho site, Ho is bonded in a 4-coordinate geometry to four equivalent Co and ten Ge atoms. All Ho–Co bond lengths are 3.34 Å. There are a spread of Ho–Ge bond distances ranging from 3.04–3.27 Å. Co is bonded in a 5-coordinate geometry to five Ho and five Ge atoms. There are a spread of Co–Ge bond distances ranging from 2.33–2.45 Å. In is bonded to eight equivalent Ho and four equivalent Ge atoms to form face-sharing InHo8Ge4 cuboctahedra. All In–Ge bond lengths are 2.99 Å. There are three inequivalent Ge sites. In the first Ge site, Ge is bonded in a 9-coordinate geometry to six Ho, one Co, one In, and one Ge atom. The Ge–Ge bond length is 2.59 Å. In the second Ge site, Ge is bonded in a 2-coordinate geometry to four Ho, two equivalent Co, and two equivalent Ge atoms. Both Ge–Ge bond lengths are 2.94 Å. In the third Ge site, Ge is bonded in a 10-coordinate geometry to five Ho, two equivalent Co, and three Ge atoms.
