Materials Data on Ho3(CoGe2)2 by Materials Project

Ho3(CoGe2)2 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are two inequivalent Ho sites. In the first Ho site, Ho is bonded in a 12-coordinate geometry to four equivalent Co and eight Ge atoms. There are a spread of Ho–Co bond distances ranging from 2.86–3.20 Å. There are a spread of Ho–Ge bond distances ranging from 2.95–3.24 Å. In the second Ho site, Ho is bonded in a 6-coordinate geometry to eight Ge atoms. There are a spread of Ho–Ge bond distances ranging from 2.96–3.32 Å. Co is bonded in a 4-coordinate geometry to four equivalent Ho and four Ge atoms. There are a spread of Co–Ge bond distances ranging from 2.34–2.43 Å. There are two inequivalent Ge sites. In the first Ge site, Ge is bonded in a 10-coordinate geometry to six Ho, three equivalent Co, and one Ge atom. The Ge–Ge bond length is 2.96 Å. In the second Ge site, Ge is bonded in a 6-coordinate geometry to six Ho, one Co, and two equivalent Ge atoms. Both Ge–Ge bond lengths are 2.71 Å.
