MnGa2Al crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one MnGa2Al cluster. Mn(1) is bonded in a single-bond geometry to one Ga(1) and one Ga(2) atom. The Mn(1)-Ga(1) bond length is 0.62 Å. The Mn(1)-Ga(2) bond length is 0.47 Å. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 2-coordinate geometry to one Mn(1) and one Ga(2) atom. The Ga(1)-Ga(2) bond length is 0.47 Å. In the second Ga site, Ga(2) is bonded in a 3-coordinate geometry to one Mn(1), one Ga(1), and one Al(1) atom. The Ga(2)-Al(1) bond length is 0.29 Å. Al(1) is bonded in a single-bond geometry to one Ga(2) atom.
