GaGe is beta-prime cadmium gold structured and crystallizes in the monoclinic P2 space group. Ga(1) is bonded in a 12-coordinate geometry to four equivalent Ga(1) and eight equivalent Ge(1) atoms. There are a spread of Ga(1)-Ga(1) bond distances ranging from 2.83-3.14 Å. There are a spread of Ga(1)-Ge(1) bond distances ranging from 2.71-3.23 Å. Ge(1) is bonded in a 11-coordinate geometry to eight equivalent Ga(1) and three equivalent Ge(1) atoms. There are two shorter (2.94 Å) and one longer (3.07 Å) Ge(1)-Ge(1) bond length.
