Hf Ga Ag Ag
HfAg2Ga crystallizes in the triclinic P1 space group. Hf(1) is bonded in a single-bond geometry to two equivalent Ag(1), two equivalent Ag(2), and one Ga(1) atom. There is one shorter (2.64 Å) and one longer (2.70 Å) Hf(1)-Ag(1) bond length. There is one shorter (3.37 Å) and one longer (3.42 Å) Hf(1)-Ag(2) bond length. The Hf(1)-Ga(1) bond length is 0.48 Å. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a 3-coordinate geometry to two equivalent Hf(1) and two equivalent Ag(2) atoms. There is one shorter (2.29 Å) and one longer (3.01 Å) Ag(1)-Ag(2) bond length. In the second Ag site, Ag(2) is bonded in a 8-coordinate geometry to two equivalent Hf(1), two equivalent Ag(1), two equivalent Ag(2), and two equivalent Ga(1) atoms. Both Ag(2)-Ag(2) bond lengths are 2.97 Å. There is one shorter (2.64 Å) and one longer (2.70 Å) Ag(2)-Ga(1) bond length. Ga(1) is bonded in a single-bond geometry to one Hf(1) and two equivalent Ag(2) atoms.
