Materials Data on SrHgO2 by Materials Project
SrHgO2 crystallizes in the trigonal R-3m space group. The structure is three-dimensional. Sr2+ is bonded to six equivalent O2- atoms to form edge-sharing SrO6 octahedra. All Sr–O bond lengths are 2.56 Å. Hg2+ is bonded in a linear geometry to two equivalent O2- atoms. Both Hg–O bond lengths are 2.00 Å. O2- is bonded to three equivalent Sr2+ and one Hg2+ atom to form a mixture of distorted edge and corner-sharing OSr3Hg tetrahedra.
