YGeAs is Cyanogen Chloride-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two YGeAs clusters. Y(1) is bonded in a linear geometry to one Ge(1) and one As(1) atom. The Y(1)-Ge(1) bond length is 0.38 Å. The Y(1)-As(1) bond length is 1.21 Å. Ge(1) is bonded in a single-bond geometry to one Y(1) atom. As(1) is bonded in a single-bond geometry to one Y(1) atom.
