TiGaGe2 is Indium-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two TiGaGe2 clusters. Ti(1) is bonded in a 2-coordinate geometry to two equivalent Ge(1) atoms. Both Ti(1)-Ge(1) bond lengths are 0.28 Å. Ga(1) is bonded in a 2-coordinate geometry to two equivalent Ge(1) atoms. Both Ga(1)-Ge(1) bond lengths are 0.59 Å. Ge(1) is bonded in a 3-coordinate geometry to one Ti(1), one Ga(1), and one Ge(1) atom. The Ge(1)-Ge(1) bond length is 0.29 Å.
