MgCoGa2 is alpha Po structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two MgCoGa2 clusters. Mg(1) is bonded in a 3-coordinate geometry to one Co(1) and two equivalent Ga(1) atoms. The Mg(1)-Co(1) bond length is 0.34 Å. Both Mg(1)-Ga(1) bond lengths are 0.31 Å. Co(1) is bonded in a 3-coordinate geometry to one Mg(1) and two equivalent Ga(1) atoms. Both Co(1)-Ga(1) bond lengths are 0.31 Å. Ga(1) is bonded in a 3-coordinate geometry to one Mg(1), one Co(1), and one Ga(1) atom. The Ga(1)-Ga(1) bond length is 0.34 Å.
