Materials Data on Ga2(Hg4Te5)3 by Materials Project
Abstract
Ga2(Hg4Te5)3 crystallizes in the monoclinic Cm space group. The structure is three-dimensional. there are eight inequivalent Hg2+ sites. In the first Hg2+ site, Hg2+ is bonded to four Te2- atoms to form HgTe4 tetrahedra that share corners with two equivalent GaTe4 tetrahedra and corners with nine HgTe4 tetrahedra. There are a spread of Hg–Te bond distances ranging from 2.85–2.89 Å. In the second Hg2+ site, Hg2+ is bonded to four Te2- atoms to form corner-sharing HgTe4 tetrahedra. There are a spread of Hg–Te bond distances ranging from 2.86–2.88 Å. In the third Hg2+ site, Hg2+ is bonded to four Te2- atoms to form HgTe4 tetrahedra that share corners with two equivalent GaTe4 tetrahedra and corners with nine HgTe4 tetrahedra. There are a spread of Hg–Te bond distances ranging from 2.85–2.89 Å. In the fourth Hg2+ site, Hg2+ is bonded to four Te2- atoms to form corner-sharing HgTe4 tetrahedra. There are two shorter (2.86 Å) and two longer (2.88 Å) Hg–Te bond lengths. In the fifth Hg2+ site, Hg2+ is bonded to four Te2- atoms to form corner-sharing HgTe4 tetrahedra. There are three shorter (2.86 Å) and one longer (2.88 Å) Hg–Te bond lengths. In the sixth Hg2+ site, Hg2+ ismore »
