Y2SnGe crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one Y2SnGe cluster. There are two inequivalent Y sites. In the first Y site, Y(1) is bonded in a distorted bent 150 degrees geometry to one Sn(1) and one Ge(1) atom. The Y(1)-Sn(1) bond length is 1.43 Å. The Y(1)-Ge(1) bond length is 2.10 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 1.02 Å. Sn(1) is bonded in a 2-coordinate geometry to one Y(1) and one Y(2) atom. Ge(1) is bonded in a distorted single-bond geometry to one Y(1) atom.
