Ga Ge As As
GaGeAs2 is Indium-like structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one GaGeAs2 cluster. Ga(1) is bonded in a 3-coordinate geometry to one Ge(1), one As(1), and one As(2) atom. The Ga(1)-Ge(1) bond length is 1.85 Å. The Ga(1)-As(1) bond length is 1.67 Å. The Ga(1)-As(2) bond length is 1.85 Å. Ge(1) is bonded in a single-bond geometry to one Ga(1) and one As(2) atom. The Ge(1)-As(2) bond length is 0.36 Å. There are two inequivalent As sites. In the first As site, As(1) is bonded in a single-bond geometry to one Ga(1) atom. In the second As site, As(2) is bonded in a single-bond geometry to one Ga(1) and one Ge(1) atom.
