Abstract
Ba6Ca6Cu9Hg3O25 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are three inequivalent Ba2+ sites. In the first Ba2+ site, Ba2+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Ba–O bond distances ranging from 2.79–2.86 Å. In the second Ba2+ site, Ba2+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Ba–O bond distances ranging from 2.79–2.86 Å. In the third Ba2+ site, Ba2+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Ba–O bond distances ranging from 2.68–2.98 Å. There are three inequivalent Ca2+ sites. In the first Ca2+ site, Ca2+ is bonded in a body-centered cubic geometry to eight O2- atoms. There are a spread of Ca–O bond distances ranging from 2.46–2.55 Å. In the second Ca2+ site, Ca2+ is bonded in a body-centered cubic geometry to eight O2- atoms. There are a spread of Ca–O bond distances ranging from 2.46–2.55 Å. In the third Ca2+ site, Ca2+ is bonded in a body-centered cubic geometry to eight O2- atoms. There are four shorter (2.46 Å) and four longer (2.57 Å) Ca–O bond lengths. There are fivemore »

The corner-sharing octahedra tilt angles range from 2–66°. In the third O2- site, O2- is bonded in a 6-coordinate geometry to two Ba2+, two Ca2+, and two Cu+2.22+ atoms. In the fourth O2- site, O2- is bonded in a 1-coordinate geometry to four Ba2+, one Cu+2.22+, and one Hg2+ atom.
