Y Y Hf Zn
Y2HfZn crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Y2HfZn clusters. Y(1) is bonded in a single-bond geometry to one Zn(1) atom. The Y(1)-Zn(1) bond length is 1.38 Å. Hf(1) is bonded in a distorted single-bond geometry to one Zn(1) atom. The Hf(1)-Zn(1) bond length is 2.33 Å. Zn(1) is bonded in a distorted L-shaped geometry to two equivalent Y(1) and one Hf(1) atom.
