ZrZnGa2 is alpha Po structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two ZrZnGa2 clusters. Zr(1) is bonded in a 3-coordinate geometry to one Zn(1) and two equivalent Ga(1) atoms. The Zr(1)-Zn(1) bond length is 0.46 Å. Both Zr(1)-Ga(1) bond lengths are 0.42 Å. Zn(1) is bonded in a 3-coordinate geometry to one Zr(1) and two equivalent Ga(1) atoms. Both Zn(1)-Ga(1) bond lengths are 0.42 Å. Ga(1) is bonded in a 3-coordinate geometry to one Zr(1), one Zn(1), and one Ga(1) atom. The Ga(1)-Ga(1) bond length is 0.46 Å.
