The material described by Ca8TiMn7O24 is (Cubic) Perovskite-derived structured and crystallizes in the cubic Pm-3m space group. Ca(1) is bonded to three equivalent O(1), three equivalent O(3), and six equivalent O(2) atoms to form CaO12 cuboctahedra that share corners with twelve equivalent Ca(1)O12 cuboctahedra, faces with six equivalent Ca(1)O12 cuboctahedra,  a faceface with one Ti(1)O6 octahedra,  a faceface with one Mn(3)O6 octahedra, faces with three equivalent Mn(1)O6 octahedra, and faces with three equivalent Mn(2)O6 octahedra. Ti(1) is bonded to six equivalent O(1) atoms to form TiO6 octahedra that share corners with six equivalent Mn(1)O6 octahedra and faces with eight equivalent Ca(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. There are three inequivalent Mn sites. In the first Mn site, Mn(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form MnO6 octahedra that share corners with two equivalent Ti(1)O6 octahedra, corners with four equivalent Mn(2)O6 octahedra, and faces with eight equivalent Ca(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. In the second Mn site, Mn(2) is bonded to two equivalent O(3) and four equivalent O(2) atoms to form MnO6 octahedra that share corners with two equivalent Mn(3)O6 octahedra, corners with four equivalent Mn(1)O6 octahedra, and faces with eight equivalent Ca(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. In the third Mn site, Mn(3) is bonded to six equivalent O(3) atoms to form MnO6 octahedra that share corners with six equivalent Mn(2)O6 octahedra and faces with eight equivalent Ca(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted linear geometry to four equivalent Ca(1), one Ti(1), and one Mn(1) atom. In the second O site, O(2) is bonded in a distorted linear geometry to four equivalent Ca(1), one Mn(1), and one Mn(2) atom. In the third O site, O(3) is bonded in a distorted linear geometry to four equivalent Ca(1), one Mn(2), and one Mn(3) atom. is represented by the CIF file [CIF]
