Materials Data on GaHgO2 by Materials Project
HgGaO2 crystallizes in the trigonal R-3m space group. The structure is three-dimensional. Hg1+ is bonded in a linear geometry to two equivalent O2- atoms. Both Hg–O bond lengths are 2.40 Å. Ga3+ is bonded to six equivalent O2- atoms to form edge-sharing GaO6 octahedra. All Ga–O bond lengths are 2.03 Å. O2- is bonded to one Hg1+ and three equivalent Ga3+ atoms to form a mixture of distorted edge and corner-sharing OGa3Hg tetrahedra.
