Mg is bonded in a 10-coordinate geometry to one Mg, two equivalent Ho, and twelve Zn atoms. The Mg–Mg bond length is 3.29 Å. Both Mg–Ho bond lengths are 3.37 Å. There are a spread of Mg–Zn bond distances ranging from 2.92–3.29 Å. Ho is bonded in a 12-coordinate geometry to three equivalent Mg, one Ho, and twelve Zn atoms. The Ho–Ho bond length is 3.09 Å. There are a spread of Ho–Zn bond distances ranging from 2.94–3.19 Å. There are six inequivalent Zn sites. In the first Zn site, Zn is bonded in a 12-coordinate geometry to three equivalent Mg, two equivalent Ho, and seven Zn atoms. There are a spread of Zn–Zn bond distances ranging from 2.50–2.80 Å.
