Abstract

Cs2Hg3OI8 crystallizes in the monoclinic Cm space group. The structure is three-dimensional. Cs is bonded in a 1-coordinate geometry to one O and eight I atoms. The Cs–O bond length is 3.26 Å. There are a spread of Cs–I bond distances ranging from 4.05–4.38 Å. There are two inequivalent Hg sites. In the first Hg site, Hg is bonded to four I atoms to form corner-sharing HgI4 tetrahedra. There are a spread of Hg–I bond distances ranging from 2.77–2.93 Å. In the second Hg site, Hg is bonded to four I atoms to form corner-sharing HgI4 tetrahedra. There are two shorter (2.76 Å) and two longer (2.97 Å) Hg–I bond lengths. O is bonded in a bent 120 degrees geometry to two equivalent Cs atoms. There are five inequivalent I sites. In the first I site, I is bonded in a 1-coordinate geometry to two equivalent Cs and one Hg atom. In the second I site, I is bonded in a distorted single-bond geometry to two equivalent Cs and one Hg atom. In the third I site, I is bonded in a distorted rectangular see-saw-like geometry to two equivalent Cs and two equivalent Hg atoms. In the fourth I site,more »« less
