Hf3(CrGa2)2 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. there are six inequivalent Hf sites. In the first Hf site, Hf is bonded in a 7-coordinate geometry to seven Ga atoms. There are a spread of Hf–Ga bond distances ranging from 2.71–3.02 Å. In the second Hf site, Hf is bonded in a 10-coordinate geometry to two equivalent Cr and eight Ga atoms. Both Hf–Cr bond lengths are 2.94 Å. There are a spread of Hf–Ga bond distances ranging from 2.92–3.12 Å. In the third Hf site, Hf is bonded in a 8-coordinate geometry to two equivalent Cr and eight Ga atoms. Both Hf–Cr bond lengths are 2.80 Å. There are a spread of Hf–Ga bond distances ranging from 2.76–3.25 Å. In the fourth Hf site, Hf is bonded in a 7-coordinate geometry to two equivalent Cr and seven Ga atoms. Both Hf–Cr bond lengths are 2.94 Å. There are a spread of Hf–Ga bond distances ranging from 2.73–2.93 Å. In the fifth Hf site, Hf is bonded in a 7-coordinate geometry to two equivalent Cr and seven Ga atoms.
