Ho6(CoGa3)7 crystallizes in the tetragonal P4/mbm space group. The structure is three-dimensional. there are two inequivalent Ho sites. In the first Ho site, Ho is bonded in a 6-coordinate geometry to six Co and twelve Ga atoms. There are four shorter (3.23 Å) and two longer (3.36 Å) Ho–Co bond lengths. There are a spread of Ho–Ga bond distances ranging from 3.08–3.27 Å. In the second Ho site, Ho is bonded in a 12-coordinate geometry to one Co and eleven Ga atoms. The Ho–Co bond length is 3.00 Å. There are a spread of Ho–Ga bond distances ranging from 2.90–3.21 Å. There are three inequivalent Co sites. In the first Co site, Co is bonded to four equivalent Ho and eight equivalent Ga atoms to form face-sharing CoHo4Ga8 cuboctahedra. All Co–Ga bond lengths are 2.81 Å. In the second Co site, Co is bonded in a 7-coordinate geometry to two equivalent Ho and seven Ga atoms. There are a spread of Co–Ga bond distances ranging from 2.39–2.47 Å. In the third Co site, Co is bonded in a 7-coordinate geometry to two equivalent Ho and seven Ga atoms. There are a spread of Co–Ga bond distances ranging from 2.41–2.55 Å. There are seven inequivalent Ga sites. In the first Ga site, Ga is bonded in a 4-coordinate geometry to three Ho, two equivalent Co, and three Ga atoms. There are two shorter (2.81 Å) and one longer (2.97 Å) Ga–Ga bond lengths. In the second Ga site, Ga is bonded to four equivalent Ho, four equivalent Co, and four equivalent Ga atoms to form face-sharing GaHo4Ga4Co4 cuboctahedra. All Ga–Ga bond lengths are 2.73 Å. In the third Ga site, Ga is bonded in a distorted pentagonal planar geometry to two equivalent Ho and three Co atoms. In the fourth Ga site, Ga is bonded in a 4-coordinate geometry to three Ho, two equivalent Co, and four Ga atoms. There are a spread of Ga–Ga bond distances ranging from 2.62–2.95 Å. In the fifth Ga site, Ga is bonded in a 10-coordinate geometry to two equivalent Ho, four equivalent Co, and four Ga atoms. In the sixth Ga site, Ga is bonded in a 10-coordinate geometry to four Ho, two Co, and four Ga atoms. In the seventh Ga site, Ga is bonded in a 10-coordinate geometry to four equivalent Ho, two equivalent Co, and four Ga atoms. Both Ga–Ga bond lengths are 2.69 Å.
