The compound described by AuCdO2 crystallizes in the orthorhombic Cmmm space group. There are two inequivalent Au sites. In the first Au site, Au(1) is bonded in a linear geometry to two equivalent O(1) atoms. In the second Au site, Au(2) is bonded in a distorted square co-planar geometry to four equivalent O(2) atoms. Cd(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form a mixture of corner, face, and edge-sharing CdO6 octahedra. The corner-sharing octahedral tilt angles are 42°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 5-coordinate geometry to one Au(1) and four equivalent Cd(1) atoms. In the second O site, O(2) is bonded to two equivalent Au(2) and two equivalent Cd(1) atoms to form a mixture of corner and edge-sharing OCd2Au2 tetrahedra. is represented by the Crystallographic Information File (CIF) [CIF]
