The structure described by YCu3(AgO3)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 Ag(1)O6 octahedra. Ag(1) is bonded to six equivalent O(1) atoms to form AgO6 octahedra that share corners with six equivalent Ag(1)O6 octahedra and faces with two equivalent Y(1)O12 cuboctahedra. The corner-sharing octahedral tilt angles are 48°. Cu(1) is bonded in a square co-planar geometry to four equivalent O(1) atoms. O(1) is bonded in a 4-coordinate geometry to one Y(1), two equivalent Ag(1), and one Cu(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
