The material structure described by Sr3Ti3(Ga2O5)4 crystallizes in the monoclinic C2/m space group. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a 7-coordinate geometry to one O(3), two equivalent O(1), two equivalent O(2), and two equivalent O(5) atoms. In the second Sr site, Sr(2) is bonded in a 6-coordinate geometry to two equivalent O(6) and four equivalent O(1) atoms. There are two inequivalent Ti sites. In the first Ti site, Ti(1) is bonded to two equivalent O(3), two equivalent O(4), and two equivalent O(5) atoms to form TiO6 octahedra that share corners with two equivalent Ga(2)O4 tetrahedra, corners with four equivalent Ga(1)O4 tetrahedra,  an edgeedge with one Ti(1)O6 octahedra, and edges with two equivalent Ti(2)O6 octahedra. In the second Ti site, Ti(2) is bonded to two equivalent O(3) and four equivalent O(5) atoms to form TiO6 octahedra that share corners with four equivalent Ga(1)O4 tetrahedra and edges with four equivalent Ti(1)O6 octahedra. 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 GaO4 tetrahedra that share  a cornercorner with one Ti(2)O6 octahedra, corners with two equivalent Ti(1)O6 octahedra, and corners with three equivalent Ga(2)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 41-63°. In the second Ga site, Ga(2) is bonded to one O(1), one O(2), one O(4), and one O(6) atom to form GaO4 tetrahedra that share  a cornercorner with one Ti(1)O6 octahedra,  a cornercorner with one Ga(2)O4 tetrahedra, and corners with three equivalent Ga(1)O4 tetrahedra. The corner-sharing octahedral tilt angles are 51°. There are six inequivalent O sites. In the first O site, O(2) is bonded in a distorted trigonal planar geometry to one Sr(1), one Ga(1), and one Ga(2) atom. In the second O site, O(3) is bonded in a distorted rectangular see-saw-like geometry to one Sr(1), one Ti(2), and two equivalent Ti(1) atoms. In the third O site, O(4) is bonded in a trigonal planar geometry to one Ti(1), one Ga(1), and one Ga(2) atom. In the fourth O site, O(5) is bonded in a 3-coordinate geometry to one Sr(1), one Ti(1), one Ti(2), and one Ga(1) atom. In the fifth O site, O(6) is bonded in a trigonal planar geometry to one Sr(2) and two equivalent Ga(2) atoms. In the sixth O site, O(1) is bonded to one Sr(1), one Sr(2), one Ga(1), and one Ga(2) atom to form a mixture of distorted corner and edge-sharing OSr2Ga2 tetrahedra. is represented by the CIF card [CIF]
