Hf Hf Re Ni
Hf2ReNi crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one Hf2ReNi cluster. There are two inequivalent Hf sites. In the first Hf site, Hf(1) is bonded in a single-bond geometry to one Ni(1) atom. The Hf(1)-Ni(1) bond length is 0.16 Å. In the second Hf site, Hf(2) is bonded in an L-shaped geometry to one Re(1) and one Ni(1) atom. The Hf(2)-Re(1) bond length is 0.57 Å. The Hf(2)-Ni(1) bond length is 0.36 Å. Re(1) is bonded in a distorted single-bond geometry to one Hf(2) atom. Ni(1) is bonded in a bent 150 degrees geometry to one Hf(1) and one Hf(2) atom.
