YNbGe2 is alpha Po structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two YNbGe2 clusters. Y(1) is bonded in an L-shaped geometry to two equivalent Ge(1) atoms. Both Y(1)-Ge(1) bond lengths are 0.99 Å. Nb(1) is bonded in an L-shaped geometry to two equivalent Ge(1) atoms. Both Nb(1)-Ge(1) bond lengths are 0.99 Å. Ge(1) is bonded in an L-shaped geometry to one Y(1) and one Nb(1) atom.
