YGa2 is hexagonal omega structure structured and crystallizes in the hexagonal P6/mmm space group. Y(1) is bonded to twelve equivalent Ga(1) atoms to form a mixture of edge and face-sharing YGa12 cuboctahedra. Ga(1) is bonded in a 9-coordinate geometry to six equivalent Y(1) and three equivalent Ga(1) atoms.
