Materials Data on Hg5(ClO2)2 by Materials Project

Abstract

Hg5(O2Cl)2 crystallizes in the orthorhombic Ibam space group. The structure is three-dimensional. there are three inequivalent Hg2+ sites. In the first Hg2+ site, Hg2+ is bonded in a distorted linear geometry to two equivalent O2- and four equivalent Cl1- atoms. Both Hg–O bond lengths are 2.11 Å. There are a spread of Hg–Cl bond distances ranging from 2.98–3.23 Å. In the second Hg2+ site, Hg2+ is bonded in a 2-coordinate geometry to four equivalent O2- and two equivalent Cl1- atoms. There are two shorter (2.08 Å) and two longer (2.79 Å) Hg–O bond lengths. Both Hg–Cl bond lengths are 3.38 Å. In the third Hg2+ site, Hg2+ is bonded in a 4-coordinate geometry to four equivalent O2- atoms. All Hg–O bond lengths are 2.32 Å. O2- is bonded to four Hg2+ atoms to form a mixture of distorted edge and corner-sharing OHg4 tetrahedra. Cl1- is bonded in a 6-coordinate geometry to six Hg2+ atoms.
