Sr(GaSi) is hexagonal omega structure-derived structured and crystallizes in the hexagonal P-6m2 space group. Sr(1) is bonded to six equivalent Ga(1) and six equivalent Si(1) atoms to form a mixture of face and edge-sharing SrGa6Si6 cuboctahedra. Ga(1) is bonded in a 9-coordinate geometry to six equivalent Sr(1) and three equivalent Si(1) atoms. Si(1) is bonded in a 9-coordinate geometry to six equivalent Sr(1) and three equivalent Ga(1) atoms.
