CaCr2Cu3(SbO6)2 crystallizes in the cubic Pn-3 space group. Ca(1) is bonded to twelve equivalent O(1) atoms to form CaO12 cuboctahedra that share faces with four equivalent Cr(1)O6 octahedra and faces with four equivalent Sb(1)O6 octahedra. Cr(1) is bonded to six equivalent O(1) atoms to form CrO6 octahedra that share corners with six equivalent Sb(1)O6 octahedra and faces with two equivalent Ca(1)O12 cuboctahedra. The corner-sharing octahedral tilt angles are 41°. Cu(1) is bonded in a square co-planar geometry to four equivalent O(1) atoms. Sb(1) is bonded to six equivalent O(1) atoms to form SbO6 octahedra that share corners with six equivalent Cr(1)O6 octahedra and faces with two equivalent Ca(1)O12 cuboctahedra. The corner-sharing octahedral tilt angles are 41°. O(1) is bonded in a 4-coordinate geometry to one Ca(1), one Cr(1), one Cu(1), and one Sb(1) atom.
