Title: Materials Data on SrHg2(ClO)2 by Materials Project

Abstract

SrHg2(OCl)2 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Sr2+ is bonded in a 8-coordinate geometry to three O2- and five Cl1- atoms. There are a spread of Sr–O bond distances ranging from 2.56–2.78 Å. There are a spread of Sr–Cl bond distances ranging from 2.97–3.31 Å. There are two inequivalent Hg2+ sites. In the first Hg2+ site, Hg2+ is bonded in a 2-coordinate geometry to three O2- and three equivalent Cl1- atoms. There are two shorter (2.12 Å) and one longer (2.60 Å) Hg–O bond lengths. There are a spread of Hg–Cl bond distances ranging from 3.12–3.34 Å. In the second Hg2+ site, Hg2+ is bonded in a distorted linear geometry to two O2- and four Cl1- atoms. There are one shorter (2.09 Å) and one longer (2.11 Å) Hg–O bond lengths. There are a spread of Hg–Cl bond distances ranging from 3.02–3.22 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded to two equivalent Sr2+ and two Hg2+ atoms to form distorted corner-sharing OSr2Hg2 tetrahedra. In the second O2- site, O2- is bonded to one Sr2+ and three Hg2+ atoms to form distorted OSrHg3 tetrahedra that share corners withmore » five equivalent OSr2Hg2 tetrahedra and an edgeedge with one OSrHg3 tetrahedra. There are two inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded in a 7-coordinate geometry to two equivalent Sr2+ and five Hg2+ atoms. In the second Cl1- site, Cl1- is bonded in a 5-coordinate geometry to three equivalent Sr2+ and two equivalent Hg2+ atoms.« less
