YSn2Sb is Cyanogen Chloride-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two YSn2Sb clusters. Y(1) is bonded in a single-bond geometry to one Sn(1) atom. The Y(1)-Sn(1) bond length is 1.15 Å. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a distorted single-bond geometry to one Y(1) and one Sb(1) atom. The Sn(1)-Sb(1) bond length is 1.91 Å. In the second Sn site, Sn(2) is bonded in a single-bond geometry to one Sb(1) atom. The Sn(2)-Sb(1) bond length is 1.91 Å. Sb(1) is bonded in a linear geometry to one Sn(1) and one Sn(2) atom.
