YPbGe2 crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two YPbGe2 clusters. Y(1) is bonded in a linear geometry to one Ge(1) and one Ge(2) atom. The Y(1)-Ge(1) bond length is 1.64 Å. The Y(1)-Ge(2) bond length is 0.58 Å. Pb(1) is bonded in a single-bond geometry to one Ge(1) atom. The Pb(1)-Ge(1) bond length is 2.70 Å. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a distorted single-bond geometry to one Y(1) and one Pb(1) atom. In the second Ge site, Ge(2) is bonded in a single-bond geometry to one Y(1) atom.
