Ge As Au
AuGeAs crystallizes in the triclinic P1 space group. Au(1) is bonded in a 9-coordinate geometry to six equivalent Au(1), two equivalent Ge(1), and one As(1) atom. All Au(1)-Au(1) bond lengths are 2.98 Å. There is one shorter (2.97 Å) and one longer (3.14 Å) Au(1)-Ge(1) bond length. The Au(1)-As(1) bond length is 3.12 Å. Ge(1) is bonded in a 1-coordinate geometry to two equivalent Au(1) and one As(1) atom. The Ge(1)-As(1) bond length is 2.19 Å. As(1) is bonded in a distorted single-bond geometry to one Au(1) and one Ge(1) atom.
