SrLaGaO4 is (La,Ba)CuO4-derived structured and crystallizes in the tetragonal I4mm space group. Sr(1) is bonded in a 9-coordinate geometry to one O(2), four equivalent O(1), and four equivalent O(3) atoms. La(1) is bonded in a 9-coordinate geometry to one O(3), four equivalent O(1), and four equivalent O(2) atoms. Ga(1) is bonded to one O(2), one O(3), and four equivalent O(1) atoms to form corner-sharing GaO6 octahedra. The corner-sharing octahedral tilt angles are 7°. There are three inequivalent O sites.
