Hf Pd Au
HfPdAu is Cyanogen Chloride-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two HfPdAu clusters. Hf(1) is bonded in a linear geometry to one Pd(1) and one Au(1) atom. The Hf(1)-Pd(1) bond length is 0.32 Å. The Hf(1)-Au(1) bond length is 0.03 Å. Pd(1) is bonded in a single-bond geometry to one Hf(1) atom. Au(1) is bonded in a single-bond geometry to one Hf(1) atom.
