The structure described by CaGa2 crystallizes in the hexagonal P6_3/mmc space group. Ca(1) is bonded in a 12-coordinate geometry to twelve equivalent Ga(1) atoms. Ga(1) is bonded in a 10-coordinate geometry to six equivalent Ca(1) and four equivalent Ga(1) atoms. is represented by the CIF card [CIF]
