Hf Hf As Pt
Hf2PtAs crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one Hf2PtAs cluster. There are two inequivalent Hf sites. In the first Hf site, Hf(1) is bonded in a linear geometry to one Pt(1) and one As(1) atom. The Hf(1)-Pt(1) bond length is 0.78 Å. The Hf(1)-As(1) bond length is 1.00 Å. In the second Hf site, Hf(2) is bonded in a single-bond geometry to one Pt(1) atom. The Hf(2)-Pt(1) bond length is 0.78 Å. Pt(1) is bonded in a linear geometry to one Hf(1) and one Hf(2) atom. As(1) is bonded in a single-bond geometry to one Hf(1) atom.
