YbSn is Tetraauricupride structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two YbSn clusters. Yb(1) is bonded in a distorted single-bond geometry to one Sn(1) atom. The Yb(1)-Sn(1) bond length is 1.73 Å. Sn(1) is bonded in a distorted single-bond geometry to one Yb(1) atom.
