Mg(ScGa)2 crystallizes in the tetragonal P4/mbm space group. Mg(1) is bonded in a distorted square co-planar geometry to four equivalent Ga(1) atoms. Sc(1) is bonded in a 6-coordinate geometry to six equivalent Ga(1) atoms. Ga(1) is bonded in a 9-coordinate geometry to two equivalent Mg(1), six equivalent Sc(1), and one Ga(1) atom.
Mg(ScGa)2 crystallizes in the tetragonal P4/mbm space group. Mg(1) is bonded in a distorted square co-planar geometry to four equivalent Ga(1) atoms. All Mg(1)-Ga(1) bond lengths are 2.87 Å. Sc(1) is bonded in a 6-coordinate geometry to six equivalent Ga(1) atoms. There are two shorter (2.80 Å) and four longer (2.90 Å) Sc(1)-Ga(1) bond lengths. Ga(1) is bonded in a 9-coordinate geometry to two equivalent Mg(1), six equivalent Sc(1), and one Ga(1) atom. The Ga(1)-Ga(1) bond length is 2.51 Å.
