SrCu3Ti4O12 crystallizes in the cubic Im-3 space group. Sr(1) is bonded to twelve equivalent O(1) atoms to form SrO12 cuboctahedra that share faces with eight equivalent Ti(1)O6 octahedra. Ti(1) is bonded to six equivalent O(1) atoms to form TiO6 octahedra that share corners with six equivalent Ti(1)O6 octahedra and faces with two equivalent Sr(1)O12 cuboctahedra. The corner-sharing octahedral tilt angles are 39°. Cu(1) is bonded in a square co-planar geometry to four equivalent O(1) atoms. O(1) is bonded in a 4-coordinate geometry to one Sr(1), two equivalent Ti(1), and one Cu(1) atom.
