The material structure described by LiSr4Mn2(GaO5)2 crystallizes in the triclinic P-1 space group. Li(1) is bonded in a square co-planar geometry to two equivalent O(1) and two equivalent O(2) atoms. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a 7-coordinate geometry to one O(3), one O(4), one O(5), two equivalent O(1), and two equivalent O(2) atoms. In the second Sr site, Sr(2) is bonded in a 3-coordinate geometry to one O(1), one O(3), one O(4), and one O(5) atom. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form distorted MnO6 octahedra that share corners with two equivalent Ga(1)O4 tetrahedra. In the second Mn site, Mn(2) is bonded in a distorted square co-planar geometry to two equivalent O(1), two equivalent O(2), and two equivalent O(4) atoms. Ga(1) is bonded to one O(3), one O(4), and two equivalent O(5) atoms to form GaO4 tetrahedra that share  a cornercorner with one Mn(1)O6 octahedra and  an edgeedge with one Ga(1)O4 tetrahedra. The corner-sharing octahedral tilt angles are 32°. There are five inequivalent O sites. In the first O site, O(1) is bonded in a 6-coordinate geometry to one Li(1), one Sr(2), two equivalent Sr(1), one Mn(1), and one Mn(2) atom. In the second O site, O(2) is bonded in a 3-coordinate geometry to one Li(1), two equivalent Sr(1), one Mn(1), and one Mn(2) atom. In the third O site, O(3) is bonded in a 4-coordinate geometry to one Sr(1), one Sr(2), one Mn(1), and one Ga(1) atom. In the fourth O site, O(4) is bonded in a 4-coordinate geometry to one Sr(1), one Sr(2), one Mn(2), and one Ga(1) atom. In the fifth O site, O(5) is bonded to one Sr(1), one Sr(2), and two equivalent Ga(1) atoms to form distorted edge-sharing OSr2Ga2 tetrahedra. is represented by the CIF file [CIF]
