description: Ho3(CuGa2)2 crystallizes in the trigonal P3m1 space group. The structure is three-dimensional. there are six inequivalent Ho sites. In the first Ho site, Ho is bonded in a 12-coordinate geometry to three equivalent Cu and nine Ga atoms. All Ho–Cu bond lengths are 2.91 Å. There are a spread of Ho–Ga bond distances ranging from 3.00–3.35 Å. In the second Ho site, Ho is bonded in a 12-coordinate geometry to three equivalent Cu and nine Ga atoms. All Ho–Cu bond lengths are 2.91 Å. There are a spread of Ho–Ga bond distances ranging from 3.00–3.35 Å. In the third Ho site, Ho is bonded in a 12-coordinate geometry to six Cu and six Ga atoms.
