The structure described by La8Al7BO24 is (Cubic) Perovskite-derived structured and crystallizes in the cubic Pm-3m space group. La(1) is bonded to three equivalent O(1), three equivalent O(3), and six equivalent O(2) atoms to form LaO12 cuboctahedra that share corners with twelve equivalent La(1)O12 cuboctahedra, faces with six equivalent La(1)O12 cuboctahedra,  a faceface with one Al(3)O6 octahedra,  a faceface with one B(1)O6 octahedra, faces with three equivalent Al(1)O6 octahedra, and faces with three equivalent Al(2)O6 octahedra. There are three inequivalent Al sites. In the first Al site, Al(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form AlO6 octahedra that share corners with two equivalent B(1)O6 octahedra, corners with four equivalent Al(2)O6 octahedra, and faces with eight equivalent La(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. In the second Al site, Al(2) is bonded to two equivalent O(3) and four equivalent O(2) atoms to form AlO6 octahedra that share corners with two equivalent Al(3)O6 octahedra, corners with four equivalent Al(1)O6 octahedra, and faces with eight equivalent La(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. In the third Al site, Al(3) is bonded to six equivalent O(3) atoms to form AlO6 octahedra that share corners with six equivalent Al(2)O6 octahedra and faces with eight equivalent La(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. B(1) is bonded to six equivalent O(1) atoms to form BO6 octahedra that share corners with six equivalent Al(1)O6 octahedra and faces with eight equivalent La(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 to four equivalent La(1), one Al(1), and one B(1) atom to form a mixture of distorted corner and face-sharing OLa4AlB octahedra. The corner-sharing octahedra are not tilted. In the second O site, O(2) is bonded in a distorted linear geometry to four equivalent La(1), one Al(1), and one Al(2) atom. In the third O site, O(3) is bonded in a distorted linear geometry to four equivalent La(1), one Al(2), and one Al(3) atom. is represented by the CIF card [CIF]
