AuGe2As is alpha Po structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two AuGe2As clusters. Au(1) is bonded in a 3-coordinate geometry to two equivalent Ge(1) and one As(1) atom. Both Au(1)-Ge(1) bond lengths are 0.78 Å. The Au(1)-As(1) bond length is 0.78 Å. Ge(1) is bonded in a 3-coordinate geometry to one Au(1), one Ge(1), and one As(1) atom. The Ge(1)-Ge(1) bond length is 0.78 Å. The Ge(1)-As(1) bond length is 0.78 Å. As(1) is bonded in a 3-coordinate geometry to one Au(1) and two equivalent Ge(1) atoms.
