The structure described by BaSrGa4 is hexagonal omega structure-derived structured and crystallizes in the hexagonal P6/mmm space group. Ba(1) is bonded to twelve equivalent Ga(1) atoms to form BaGa12 cuboctahedra that share edges with twelve equivalent Sr(1)Ga12 cuboctahedra, faces with two equivalent Sr(1)Ga12 cuboctahedra, and faces with six equivalent Ba(1)Ga12 cuboctahedra. Sr(1) is bonded to twelve equivalent Ga(1) atoms to form SrGa12 cuboctahedra that share edges with twelve equivalent Ba(1)Ga12 cuboctahedra, faces with two equivalent Ba(1)Ga12 cuboctahedra, and faces with six equivalent Sr(1)Ga12 cuboctahedra. Ga(1) is bonded in a 9-coordinate geometry to three equivalent Ba(1), three equivalent Sr(1), and three equivalent Ga(1) atoms. is represented by the CIF card [CIF]
