Hf Mg Mg Ga
Mg2HfGa crystallizes in the triclinic P1 space group. There are two inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a 3-coordinate geometry to one Mg(2) and two equivalent Ga(1) atoms. The Mg(1)-Mg(2) bond length is 2.09 Å. There is one shorter (2.53 Å) and one longer (2.83 Å) Mg(1)-Ga(1) bond length. In the second Mg site, Mg(2) is bonded in a distorted trigonal non-coplanar geometry to one Mg(1) and two equivalent Hf(1) atoms. There is one shorter (2.02 Å) and one longer (2.20 Å) Mg(2)-Hf(1) bond length. Hf(1) is bonded in a single-bond geometry to two equivalent Mg(2) and one Ga(1) atom. The Hf(1)-Ga(1) bond length is 1.03 Å. Ga(1) is bonded in a distorted single-bond geometry to two equivalent Mg(1) and one Hf(1) atom.
