Ho7Co6Sn23 crystallizes in the trigonal P-3m1 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 six equivalent Co and twelve Sn atoms. All Ho–Co bond lengths are 3.44 Å. All Ho–Sn bond lengths are 3.36 Å. In the second Ho site, Ho is bonded in a 12-coordinate geometry to two equivalent Co and ten Sn atoms. Both Ho–Co bond lengths are 3.18 Å. There are a spread of Ho–Sn bond distances ranging from 3.09–3.41 Å. Co is bonded in a 9-coordinate geometry to three Ho and six Sn atoms. There are a spread of Co–Sn bond distances ranging from 2.59–2.79 Å. There are six inequivalent Sn sites. In the first Sn site, Sn is bonded in a 6-coordinate geometry to six equivalent Sn atoms. All Sn–Sn bond lengths are 2.99 Å. In the second Sn site, Sn is bonded in a 3-coordinate geometry to three equivalent Ho, three equivalent Co, and one Sn atom. The Sn–Sn bond length is 2.94 Å. In the third Sn site, Sn is bonded in a 4-coordinate geometry to three equivalent Ho and one Sn atom. In the fourth Sn site, Sn is bonded in a 2-coordinate geometry to three Ho and two equivalent Co atoms. In the fifth Sn site, Sn is bonded in a 5-coordinate geometry to four equivalent Ho, one Co, and one Sn atom. The Sn–Sn bond length is 3.20 Å. In the sixth Sn site, Sn is bonded in a 7-coordinate geometry to three Ho, two equivalent Co, and two Sn atoms.
