Title: Materials Data on Ga2HgO4 by Materials Project

Abstract

HgGa2O4 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Hg2+ is bonded in a 2-coordinate geometry to three O2- atoms. There are a spread of Hg–O bond distances ranging from 2.06–2.67 Å. There are two inequivalent Ga3+ sites. In the first Ga3+ site, Ga3+ is bonded to five O2- atoms to form a mixture of distorted edge and corner-sharing GaO5 square pyramids. There are a spread of Ga–O bond distances ranging from 1.88–2.00 Å. In the second Ga3+ site, Ga3+ is bonded to five O2- atoms to form a mixture of edge and corner-sharing GaO5 square pyramids. There are a spread of Ga–O bond distances ranging from 1.94–1.98 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a trigonal planar geometry to three Ga3+ atoms. In the second O2- site, O2- is bonded in a distorted trigonal planar geometry to one Hg2+ and two equivalent Ga3+ atoms. In the third O2- site, O2- is bonded to one Hg2+ and three Ga3+ atoms to form distorted corner-sharing OGa3Hg tetrahedra. In the fourth O2- site, O2- is bonded in a distorted trigonal planar geometry to one Hg2+ and two equivalent Ga3+ atoms.
