SrHgO2 crystallizes in the trigonal R-3m space group. Sr(1) is bonded to six equivalent O(1) atoms to form edge-sharing SrO6 octahedra. Hg(1) is bonded in a linear geometry to two equivalent O(1) atoms. O(1) is bonded to three equivalent Sr(1) and one Hg(1) atom to form a mixture of distorted corner and edge-sharing OSr3Hg tetrahedra.
SrHgO2 crystallizes in the trigonal R-3m space group. Sr(1) is bonded to six equivalent O(1) atoms to form edge-sharing SrO6 octahedra. All Sr(1)-O(1) bond lengths are 2.53 Å. Hg(1) is bonded in a linear geometry to two equivalent O(1) atoms. Both Hg(1)-O(1) bond lengths are 1.98 Å. O(1) is bonded to three equivalent Sr(1) and one Hg(1) atom to form a mixture of distorted corner and edge-sharing OSr3Hg tetrahedra.
