Hf Pt Pt Au
HfPt2Au crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two HfPt2Au clusters. Hf(1) is bonded in a single-bond geometry to one Pt(1) atom. The Hf(1)-Pt(1) bond length is 0.40 Å. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a single-bond geometry to one Hf(1) and one Au(1) atom. The Pt(1)-Au(1) bond length is 2.42 Å. In the second Pt site, Pt(2) is bonded in a single-bond geometry to one Au(1) atom. The Pt(2)-Au(1) bond length is 2.42 Å. Au(1) is bonded in a linear geometry to one Pt(1) and one Pt(2) atom.
