The material described by Sr3Ga2O5Cl2 is Esseneite-like structured and crystallizes in the orthorhombic P2_12_12_1 space group. There are three inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a 8-coordinate geometry to one O(1), one O(2), one O(3), one O(4), two equivalent Cl(1), and two equivalent Cl(2) atoms. In the second Sr site, Sr(2) is bonded in a 8-coordinate geometry to one O(1), one O(2), one O(3), one O(5), two equivalent Cl(1), and two equivalent Cl(2) atoms. In the third Sr site, Sr(3) is bonded in a 6-coordinate geometry to one O(2), one O(3), one O(4), one O(5), two equivalent Cl(1), and two equivalent Cl(2) atoms. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded to one O(1), one O(2), one O(4), and one O(5) atom to form corner-sharing GaO4 tetrahedra. In the second Ga site, Ga(2) is bonded to one O(1), one O(3), one O(4), and one O(5) atom to form corner-sharing GaO4 tetrahedra. There are five inequivalent O sites. In the first O site, O(3) is bonded to one Sr(1), one Sr(2), one Sr(3), and one Ga(2) atom to form corner-sharing OSr3Ga tetrahedra. In the second O site, O(4) is bonded in a 4-coordinate geometry to one Sr(1), one Sr(3), one Ga(1), and one Ga(2) atom. In the third O site, O(5) is bonded in a 4-coordinate geometry to one Sr(2), one Sr(3), one Ga(1), and one Ga(2) atom. In the fourth O site, O(1) is bonded in a 4-coordinate geometry to one Sr(1), one Sr(2), one Ga(1), and one Ga(2) atom. In the fifth O site, O(2) is bonded to one Sr(1), one Sr(2), one Sr(3), and one Ga(1) atom to form corner-sharing OSr3Ga tetrahedra. There are two inequivalent Cl sites. In the first Cl site, Cl(1) is bonded in a 6-coordinate geometry to two equivalent Sr(1), two equivalent Sr(2), and two equivalent Sr(3) atoms. In the second Cl site, Cl(2) is bonded in a 6-coordinate geometry to two equivalent Sr(1), two equivalent Sr(2), and two equivalent Sr(3) atoms. is represented by the CIF card [CIF]
