HgGaO2 crystallizes in the trigonal R-3m space group. Hg(1) is bonded in a linear geometry to two equivalent O(1) atoms. Ga(1) is bonded to six equivalent O(1) atoms to form edge-sharing GaO6 octahedra. O(1) is bonded to one Hg(1) and three equivalent Ga(1) atoms to form a mixture of distorted corner and edge-sharing OGa3Hg tetrahedra.
HgGaO2 crystallizes in the trigonal R-3m space group. Hg(1) is bonded in a linear geometry to two equivalent O(1) atoms. Both Hg(1)-O(1) bond lengths are 2.40 Å. Ga(1) is bonded to six equivalent O(1) atoms to form edge-sharing GaO6 octahedra. All Ga(1)-O(1) bond lengths are 2.03 Å. O(1) is bonded to one Hg(1) and three equivalent Ga(1) atoms to form a mixture of distorted corner and edge-sharing OGa3Hg tetrahedra.
