Sr(CdGa)2 crystallizes in the tetragonal I4/mmm space group. Sr(1) is bonded in a 16-coordinate geometry to eight equivalent Cd(1) and eight equivalent Ga(1) atoms. Cd(1) is bonded to four equivalent Sr(1) and four equivalent Ga(1) atoms to form a mixture of distorted corner, edge, and face-sharing CdSr4Ga4 tetrahedra. Ga(1) is bonded in a 9-coordinate geometry to four equivalent Sr(1), four equivalent Cd(1), and one Ga(1) atom.
