CaCu3(PtO3)4 crystallizes in the cubic Im-3 space group. Ca(1) is bonded to twelve equivalent O(1) atoms to form CaO12 cuboctahedra that share faces with eight equivalent Pt(1)O6 octahedra. Pt(1) is bonded to six equivalent O(1) atoms to form PtO6 octahedra that share corners with six equivalent Pt(1)O6 octahedra and faces with two equivalent Ca(1)O12 cuboctahedra. The corner-sharing octahedral tilt angles are 44°. Cu(1) is bonded in a square co-planar geometry to four equivalent O(1) atoms. O(1) is bonded to one Ca(1), two equivalent Pt(1), and one Cu(1) atom to form a mixture of distorted edge and corner-sharing OCaCuPt2 tetrahedra.
