Hf Hf Re Pt
Hf2RePt crystallizes in the monoclinic Pm space group. Hf(1) is bonded in a 4-coordinate geometry to one Hf(1), one Re(1), and two equivalent Pt(1) atoms. The Hf(1)-Hf(1) bond length is 1.38 Å. The Hf(1)-Re(1) bond length is 2.86 Å. There is one shorter (2.49 Å) and one longer (3.11 Å) Hf(1)-Pt(1) bond length. Re(1) is bonded in a single-bond geometry to two equivalent Hf(1) and one Pt(1) atom. The Re(1)-Pt(1) bond length is 0.98 Å. Pt(1) is bonded in a 1-coordinate geometry to four equivalent Hf(1) and one Re(1) atom.
