The crystal structure described by BaZn(AgO2)4 crystallizes in the trigonal P-31m space group. Ba(1) is bonded to six equivalent O(1) and six equivalent O(2) atoms to form BaO12 cuboctahedra that share edges with six equivalent Ba(1)O12 cuboctahedra, edges with twelve equivalent Ag(1)O4 trigonal pyramids, and faces with two equivalent Zn(1)O6 octahedra. Ag(1) is bonded to one O(2) and three equivalent O(1) atoms to form AgO4 trigonal pyramids that share corners with three equivalent Zn(1)O6 octahedra, corners with four equivalent Ag(1)O4 trigonal pyramids, and edges with three equivalent Ba(1)O12 cuboctahedra. The corner-sharing octahedral tilt angles are 58°. Zn(1) is bonded to six equivalent O(1) atoms to form ZnO6 octahedra that share corners with twelve equivalent Ag(1)O4 trigonal pyramids and faces with two equivalent Ba(1)O12 cuboctahedra. There are two inequivalent O sites. In the first O site, O(1) is bonded to one Ba(1), two equivalent Ag(1), and one Zn(1) atom to form a mixture of distorted corner and edge-sharing OBaZnAg2 tetrahedra. In the second O site, O(2) is bonded in a linear geometry to three equivalent Ba(1) and two equivalent Ag(1) atoms. is represented by the CIF file [CIF]
