The crystal structure described by YCu3(SbO3)4 crystallizes in the cubic Im-3 space group. Y(1) is bonded to twelve equivalent O(1) atoms to form YO12 cuboctahedra that share faces with eight equivalent Sb(1)O6 octahedra. 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 Sb(1)O6 octahedra and faces with two equivalent Y(1)O12 cuboctahedra. The corner-sharing octahedral tilt angles are 41°. O(1) is bonded to one Y(1), one Cu(1), and two equivalent Sb(1) atoms to form a mixture of distorted corner and edge-sharing OYCuSb2 tetrahedra. is represented by the Crystallographic Information File (CIF) [CIF]
