Hf Ga Ga Pd
HfPdGa2 crystallizes in the monoclinic Cm space group. Hf(1) is bonded in a distorted single-bond geometry to one Pd(1) and one Ga(1) atom. The Hf(1)-Pd(1) bond length is 2.30 Å. The Hf(1)-Ga(1) bond length is 0.61 Å. Pd(1) is bonded in a 1-coordinate geometry to one Hf(1) and one Ga(2) atom. The Pd(1)-Ga(2) bond length is 3.01 Å. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a single-bond geometry to one Hf(1) and three equivalent Ga(2) atoms. There is one shorter (2.07 Å) and two longer (2.69 Å) Ga(1)-Ga(2) bond lengths. In the second Ga site, Ga(2) is bonded in a 4-coordinate geometry to one Pd(1) and three equivalent Ga(1) atoms.
