AgCdO2 crystallizes in the monoclinic C2/m space group. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a square co-planar geometry to two equivalent O(1) and four equivalent O(2) atoms. In the second Ag site, Ag(2) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form distorted AgO6 octahedra that share edges with two equivalent Ag(2)O6 octahedra and edges with eight equivalent Cd(1)O6 octahedra. Cd(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form CdO6 octahedra that share corners with six equivalent Cd(1)O6 octahedra, edges with four equivalent Ag(2)O6 octahedra, and edges with four equivalent Cd(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 9-22°. There are two inequivalent O sites. In the first O site, O(1) is bonded to one Ag(1), one Ag(2), and four equivalent Cd(1) atoms to form a mixture of edge and corner-sharing OCd4Ag2 octahedra. The corner-sharing octahedra are not tilted. In the second O site, O(2) is bonded in a 6-coordinate geometry to two equivalent Ag(1), two equivalent Ag(2), and two equivalent Cd(1) atoms.
AgCdO2 crystallizes in the monoclinic C2/m space group. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a square co-planar geometry to two equivalent O(1) and four equivalent O(2) atoms. Both Ag(1)-O(1) bond lengths are 2.13 Å. There are two shorter (2.10 Å) and two longer (2.82 Å) Ag(1)-O(2) bond lengths. In the second Ag site, Ag(2) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form distorted AgO6 octahedra that share edges with two equivalent Ag(2)O6 octahedra and edges with eight equivalent Cd(1)O6 octahedra. Both Ag(2)-O(1) bond lengths are 2.53 Å. There are two shorter (2.16 Å) and two longer (2.70 Å) Ag(2)-O(2) bond lengths. Cd(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form CdO6 octahedra that share corners with six equivalent Cd(1)O6 octahedra, edges with four equivalent Ag(2)O6 octahedra, and edges with four equivalent Cd(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 9-22°. Both Cd(1)-O(2) bond lengths are 2.37 Å. There are two shorter (2.39 Å) and two longer (2.48 Å) Cd(1)-O(1) bond lengths. There are two inequivalent O sites. In the first O site, O(1) is bonded to one Ag(1), one Ag(2), and four equivalent Cd(1) atoms to form a mixture of edge and corner-sharing OCd4Ag2 octahedra.
