Y2SnSb crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one Y2SnSb cluster. There are two inequivalent Y sites. In the first Y site, Y(1) is bonded in a distorted single-bond geometry to one Sn(1) and one Sb(1) atom. The Y(1)-Sn(1) bond length is 1.25 Å. The Y(1)-Sb(1) bond length is 0.67 Å. In the second Y site, Y(2) is bonded in a single-bond geometry to one Sn(1) atom. The Y(2)-Sn(1) bond length is 1.46 Å. Sn(1) is bonded in a distorted T-shaped geometry to one Y(1), one Y(2), and one Sb(1) atom. The Sn(1)-Sb(1) bond length is 1.27 Å. Sb(1) is bonded in a single-bond geometry to one Y(1) and one Sn(1) atom.
