Y Hf Sn Sn
SnYHfSn crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one HfSn cluster and one SnY cluster. In the HfSn cluster, Hf(1) is bonded in a distorted single-bond geometry to one Sn(2) atom. The Hf(1)-Sn(2) bond length is 1.09 Å. Sn(2) is bonded in a single-bond geometry to one Hf(1) atom. In the SnY cluster, Y(1) is bonded in a single-bond geometry to one Sn(1) atom. The Y(1)-Sn(1) bond length is 0.83 Å. Sn(1) is bonded in a distorted single-bond geometry to one Y(1) atom.
