The material structure described by BaSr7Ti8O24 is (Cubic) Perovskite-derived structured and crystallizes in the cubic Pm-3m space group. Ba(1) is bonded to twelve equivalent O(1) atoms to form BaO12 cuboctahedra that share corners with twelve equivalent Sr(2)O12 cuboctahedra, faces with six equivalent Sr(1)O12 cuboctahedra, and faces with eight equivalent Ti(1)O6 octahedra. There are three inequivalent Sr sites. In the first Sr site, Sr(1) is bonded to four equivalent O(2) and eight equivalent O(1) atoms to form SrO12 cuboctahedra that share corners with four equivalent Sr(3)O12 cuboctahedra, corners with eight equivalent Sr(1)O12 cuboctahedra, faces with two equivalent Ba(1)O12 cuboctahedra, faces with four equivalent Sr(2)O12 cuboctahedra, and faces with eight equivalent Ti(1)O6 octahedra. In the second Sr site, Sr(2) is bonded to four equivalent O(1) and eight equivalent O(2) atoms to form SrO12 cuboctahedra that share corners with four equivalent Ba(1)O12 cuboctahedra, corners with eight equivalent Sr(2)O12 cuboctahedra, faces with two equivalent Sr(3)O12 cuboctahedra, faces with four equivalent Sr(1)O12 cuboctahedra, and faces with eight equivalent Ti(1)O6 octahedra. In the third Sr site, Sr(3) is bonded to twelve equivalent O(2) atoms to form SrO12 cuboctahedra that share corners with twelve equivalent Sr(1)O12 cuboctahedra, faces with six equivalent Sr(2)O12 cuboctahedra, and faces with eight equivalent Ti(1)O6 octahedra. Ti(1) is bonded to three equivalent O(1) and three equivalent O(2) atoms to form TiO6 octahedra that share corners with six equivalent Ti(1)O6 octahedra,  a faceface with one Ba(1)O12 cuboctahedra,  a faceface with one Sr(3)O12 cuboctahedra, faces with three equivalent Sr(1)O12 cuboctahedra, and faces with three equivalent Sr(2)O12 cuboctahedra. The corner-sharing octahedral tilt angles range from 0-2°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted linear geometry to one Ba(1), one Sr(2), two equivalent Sr(1), and two equivalent Ti(1) atoms. In the second O site, O(2) is bonded in a distorted linear geometry to one Sr(1), one Sr(3), two equivalent Sr(2), and two equivalent Ti(1) atoms. is represented by the CIF card [CIF]
