TaReGa2 is alpha Po structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two TaReGa2 clusters. Ta(1) is bonded in a 3-coordinate geometry to one Re(1) and two equivalent Ga(1) atoms. The Ta(1)-Re(1) bond length is 0.23 Å. Both Ta(1)-Ga(1) bond lengths are 0.28 Å. Re(1) is bonded in a 3-coordinate geometry to one Ta(1) and two equivalent Ga(1) atoms. Both Re(1)-Ga(1) bond lengths are 0.28 Å. Ga(1) is bonded in a 3-coordinate geometry to one Ta(1), one Re(1), and one Ga(1) atom. The Ga(1)-Ga(1) bond length is 0.23 Å.
