Hf Ru Ru Pt
HfRu2Pt crystallizes in the triclinic P1 space group. Hf(1) is bonded in a 1-coordinate geometry to one Ru(2), two equivalent Ru(1), and one Pt(1) atom. The Hf(1)-Ru(2) bond length is 3.15 Å. There is one shorter (2.01 Å) and one longer (2.14 Å) Hf(1)-Ru(1) bond length. The Hf(1)-Pt(1) bond length is 1.46 Å. There are two inequivalent Ru sites. In the first Ru site, Ru(1) is bonded in a 4-coordinate geometry to two equivalent Hf(1), one Ru(2), and one Pt(1) atom. The Ru(1)-Ru(2) bond length is 1.82 Å. The Ru(1)-Pt(1) bond length is 2.06 Å. In the second Ru site, Ru(2) is bonded in a 3-coordinate geometry to one Hf(1), one Ru(1), and one Pt(1) atom. The Ru(2)-Pt(1) bond length is 1.82 Å. Pt(1) is bonded in a distorted single-bond geometry to one Hf(1), one Ru(1), and one Ru(2) atom.
