ScAgGa2 is alpha Po structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two ScAgGa2 clusters. Sc(1) is bonded in a distorted L-shaped geometry to one Ag(1) and two equivalent Ga(1) atoms. The Sc(1)-Ag(1) bond length is 1.05 Å. Both Sc(1)-Ga(1) bond lengths are 0.81 Å. Ag(1) is bonded in a 3-coordinate geometry to one Sc(1) and two equivalent Ga(1) atoms. Both Ag(1)-Ga(1) bond lengths are 0.81 Å. Ga(1) is bonded in a distorted L-shaped geometry to one Sc(1) and one Ag(1) atom.
