Cu3PbSn4O12 crystallizes in the cubic Im-3 space group. Cu(1) is bonded in a square co-planar geometry to four equivalent O(1) atoms. Pb(1) is bonded to twelve equivalent O(1) atoms to form PbO12 cuboctahedra that share faces with eight equivalent Sn(1)O6 octahedra. 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 Pb(1)O12 cuboctahedra. The corner-sharing octahedral tilt angles are 43°. O(1) is bonded in a distorted trigonal planar geometry to one Cu(1), one Pb(1), and two equivalent Sn(1) atoms.
