Ho4MnGe8 crystallizes in the orthorhombic Pmm2 space group. The structure is three-dimensional. there are four inequivalent Ho sites. In the first Ho site, Ho is bonded in a 10-coordinate geometry to ten Ge atoms. There are a spread of Ho–Ge bond distances ranging from 2.93–3.23 Å. In the second Ho site, Ho is bonded in a 10-coordinate geometry to ten Ge atoms. There are a spread of Ho–Ge bond distances ranging from 2.97–3.14 Å. In the third Ho site, Ho is bonded in a 4-coordinate geometry to four equivalent Mn and ten Ge atoms. All Ho–Mn bond lengths are 3.22 Å. There are a spread of Ho–Ge bond distances ranging from 3.05–3.38 Å. In the fourth Ho site, Ho is bonded in a 10-coordinate geometry to ten Ge atoms. There are a spread of Ho–Ge bond distances ranging from 3.00–3.26 Å. Mn is bonded in a 5-coordinate geometry to four equivalent Ho and five Ge atoms. There are two shorter (2.33 Å) and three longer (2.37 Å) Mn–Ge bond lengths. There are eight inequivalent Ge sites. In the first Ge site, Ge is bonded in a 1-coordinate geometry to six Ho, one Mn, and two equivalent Ge atoms. Both Ge–Ge bond lengths are 2.62 Å. In the second Ge site, Ge is bonded in a 8-coordinate geometry to six Ho and two equivalent Ge atoms. Both Ge–Ge bond lengths are 2.64 Å. In the third Ge site, Ge is bonded in a 8-coordinate geometry to six Ho and two equivalent Ge atoms. In the fourth Ge site, Ge is bonded in a 4-coordinate geometry to six Ho and two equivalent Ge atoms. In the fifth Ge site, Ge is bonded in a 2-coordinate geometry to four Ho and two equivalent Mn atoms. In the sixth Ge site, Ge is bonded in a 8-coordinate geometry to four Ho and four equivalent Ge atoms. All Ge–Ge bond lengths are 2.90 Å. In the seventh Ge site, Ge is bonded in a 2-coordinate geometry to four Ho and two equivalent Mn atoms. In the eighth Ge site, Ge is bonded in a 8-coordinate geometry to four Ho and four equivalent Ge atoms.
