The compound described by HoCo3Ga2 crystallizes in the hexagonal P6/mmm space group. There are two inequivalent Ho sites. In the first Ho site, Ho(1) is bonded in a hexagonal planar geometry to six equivalent Co(2) and twelve equivalent Ga(1) atoms. In the second Ho site, Ho(2) is bonded in a 18-coordinate geometry to six equivalent Co(1), six equivalent Co(2), and six equivalent Ga(1) atoms. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded to four equivalent Ho(2), four equivalent Co(2), and four equivalent Ga(1) atoms to form a mixture of face and corner-sharing CoHo4Ga4Co4 cuboctahedra. In the second Co site, Co(2) is bonded in a 9-coordinate geometry to one Ho(1), two equivalent Ho(2), two equivalent Co(1), and four equivalent Ga(1) atoms. Ga(1) is bonded in a 12-coordinate geometry to two equivalent Ho(1), two equivalent Ho(2), two equivalent Co(1), four equivalent Co(2), and two equivalent Ga(1) atoms. is represented by the CIF file [CIF]
