CrAuO2 crystallizes in the trigonal R-3m space group. Cr(1) is bonded to six equivalent O(1) atoms to form edge-sharing CrO6 octahedra. Au(1) is bonded in a linear geometry to two equivalent O(1) atoms. O(1) is bonded to three equivalent Cr(1) and one Au(1) atom to form a mixture of distorted corner and edge-sharing OCr3Au tetrahedra.
CrAuO2 crystallizes in the trigonal R-3m space group. Cr(1) is bonded to six equivalent O(1) atoms to form edge-sharing CrO6 octahedra. All Cr(1)-O(1) bond lengths are 2.00 Å. Au(1) is bonded in a linear geometry to two equivalent O(1) atoms. Both Au(1)-O(1) bond lengths are 2.08 Å. O(1) is bonded to three equivalent Cr(1) and one Au(1) atom to form a mixture of distorted corner and edge-sharing OCr3Au tetrahedra.
