The structure described by Sr(GaGe) 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 Ge(1) atoms to form a mixture of face and edge-sharing SrGa6Ge6 cuboctahedra. Ga(1) is bonded in a distorted trigonal planar geometry to six equivalent Sr(1) and three equivalent Ge(1) atoms. Ge(1) is bonded in a 9-coordinate geometry to six equivalent Sr(1) and three equivalent Ga(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
