The structure described by SrCu3(SnO3)4 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 Sn(1)O6 octahedra. Cu(1) is bonded in a square co-planar geometry to four equivalent O(1) atoms. Sn(1) is bonded to six equivalent O(1) atoms to form SnO6 octahedra that share corners with six equivalent Sn(1)O6 octahedra and faces with two equivalent Sr(1)O12 cuboctahedra. The corner-sharing octahedral tilt angles are 43°. O(1) is bonded to one Sr(1), one Cu(1), and two equivalent Sn(1) atoms to form a mixture of distorted edge and corner-sharing OSrCuSn2 tetrahedra. is represented by the CIF card [CIF]
