Abstract

Ta2Hg3S(O2F5)2 crystallizes in the orthorhombic Fdd2 space group. The structure is three-dimensional. Ta5+ is bonded to one O2- and five F1- atoms to form TaOF5 octahedra that share a cornercorner with one SO4 tetrahedra. The Ta–O bond length is 2.08 Å. There are a spread of Ta–F bond distances ranging from 1.90–1.93 Å. There are two inequivalent Hg2+ sites. In the first Hg2+ site, Hg2+ is bonded in a 6-coordinate geometry to two equivalent Hg2+, two equivalent O2-, and two equivalent F1- atoms. Both Hg–Hg bond lengths are 2.65 Å. Both Hg–O bond lengths are 3.17 Å. Both Hg–F bond lengths are 3.06 Å. In the second Hg2+ site, Hg2+ is bonded in a 2-coordinate geometry to one Hg2+, one O2-, and one F1- atom. The Hg–O bond length is 2.36 Å. The Hg–F bond length is 2.89 Å. S2+ is bonded to four O2- atoms to form SO4 tetrahedra that share corners with two equivalent TaOF5 octahedra. The corner-sharing octahedral tilt angles are 40°. There is two shorter (1.47 Å) and two longer (1.51 Å) S–O bond length. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 150 degrees geometrymore »« less
