YHfW2 crystallizes in the triclinic P1 space group. Y(1) is bonded in a 4-coordinate geometry to one Hf(1), one W(1), and two equivalent W(2) atoms. The Y(1)-Hf(1) bond length is 2.08 Å. The Y(1)-W(1) bond length is 2.41 Å. There is one shorter (3.11 Å) and one longer (3.17 Å) Y(1)-W(2) bond length. Hf(1) is bonded in a 1-coordinate geometry to one Y(1), one W(1), and one W(2) atom. The Hf(1)-W(1) bond length is 1.50 Å. The Hf(1)-W(2) bond length is 2.09 Å. There are two inequivalent W sites. In the first W site, W(1) is bonded in a 1-coordinate geometry to one Y(1), one Hf(1), and one W(2) atom. The W(1)-W(2) bond length is 1.50 Å. In the second W site, W(2) is bonded in a 4-coordinate geometry to two equivalent Y(1), one Hf(1), and one W(1) atom.
