The structure described by Sr2CuGaO3S crystallizes in the tetragonal P4/nmm space group. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a 4-coordinate geometry to four equivalent S(1) and four equivalent O(2) atoms. In the second Sr site, Sr(2) is bonded in a 9-coordinate geometry to four equivalent O(2) and five equivalent O(1) atoms. Cu(1) is bonded to four equivalent S(1) atoms to form a mixture of corner and edge-sharing CuS4 tetrahedra. Ga(1) is bonded to one O(1) and four equivalent O(2) atoms to form corner-sharing GaO5 square pyramids. S(1) is bonded in a 8-coordinate geometry to four equivalent Sr(1) and four equivalent Cu(1) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded to five equivalent Sr(2) and one Ga(1) atom to form distorted OSr5Ga octahedra that share corners with four equivalent O(1)Sr5Ga octahedra, corners with twelve equivalent O(2)Sr4Ga2 octahedra, edges with eight equivalent O(1)Sr5Ga octahedra, and faces with four equivalent O(2)Sr4Ga2 octahedra. The corner-sharing octahedral tilt angles range from 12-56°. In the second O site, O(2) is bonded to two equivalent Sr(1), two equivalent Sr(2), and two equivalent Ga(1) atoms to form distorted OSr4Ga2 octahedra that share corners with two equivalent O(2)Sr4Ga2 octahedra, corners with six equivalent O(1)Sr5Ga octahedra, edges with two equivalent O(2)Sr4Ga2 octahedra, faces with two equivalent O(1)Sr5Ga octahedra, and faces with four equivalent O(2)Sr4Ga2 octahedra. The corner-sharing octahedral tilt angles range from 22-56°. is represented by the Crystallographic Information File (CIF) [CIF]
