The compound described by K9U6BiO24 is (Cubic) Perovskite-derived structured and crystallizes in the cubic Pm-3m space group. There are two inequivalent K sites. In the first K site, K(1) is bonded to six equivalent O(1) atoms to form KO6 octahedra that share corners with six equivalent U(1)O6 octahedra and faces with eight equivalent K(2)O12 cuboctahedra. The corner-sharing octahedra are not tilted. In the second K site, K(2) is bonded to three equivalent O(1), three equivalent O(3), and six equivalent O(2) atoms to form KO12 cuboctahedra that share corners with twelve equivalent K(2)O12 cuboctahedra, faces with six equivalent K(2)O12 cuboctahedra,  a faceface with one K(1)O6 octahedra,  a faceface with one Bi(1)O6 octahedra, faces with three equivalent U(1)O6 octahedra, and faces with three equivalent U(2)O6 octahedra. There are two inequivalent U sites. In the first U site, U(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form UO6 octahedra that share corners with two equivalent K(1)O6 octahedra, corners with four equivalent U(2)O6 octahedra, and faces with eight equivalent K(2)O12 cuboctahedra. The corner-sharing octahedra are not tilted. In the second U site, U(2) is bonded to two equivalent O(3) and four equivalent O(2) atoms to form UO6 octahedra that share corners with two equivalent Bi(1)O6 octahedra, corners with four equivalent U(1)O6 octahedra, and faces with eight equivalent K(2)O12 cuboctahedra. The corner-sharing octahedra are not tilted. Bi(1) is bonded to six equivalent O(3) atoms to form BiO6 octahedra that share corners with six equivalent U(2)O6 octahedra and faces with eight equivalent K(2)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 6-coordinate geometry to one K(1), four equivalent K(2), and one U(1) atom. In the second O site, O(2) is bonded in a distorted linear geometry to four equivalent K(2), one U(1), and one U(2) atom. In the third O site, O(3) is bonded in a 6-coordinate geometry to four equivalent K(2), one U(2), and one Bi(1) atom. is represented by the CIF file [CIF]
