GaGe2 crystallizes in the triclinic P-1 space group. Ga(1) is bonded in a distorted bent 150 degrees geometry to one Ge(1) and one Ge(2) atom. The Ga(1)-Ge(1) bond length is 2.55 Å. The Ga(1)-Ge(2) bond length is 2.02 Å. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 6-coordinate geometry to one Ga(1), two equivalent Ge(2), and three equivalent Ge(1) atoms. There is one shorter (2.43 Å) and one longer (2.69 Å) Ge(1)-Ge(2) bond length. There is one shorter (2.62 Å) and two longer (2.96 Å) Ge(1)-Ge(1) bond lengths. In the second Ge site, Ge(2) is bonded in a distorted linear geometry to one Ga(1), one Ge(2), and two equivalent Ge(1) atoms. The Ge(2)-Ge(2) bond length is 1.40 Å.
