In the third Ca2+ site, Ca2+ is bonded to six O2- atoms to form distorted edge-sharing CaO6 octahedra. There are a spread of Ca–O bond distances ranging from 2.33–2.54 Å. In the fourth Ca2+ site, Ca2+ is bonded to six O2- atoms to form distorted edge-sharing CaO6 octahedra. There are a spread of Ca–O bond distances ranging from 2.33–2.57 Å. In the fifth Ca2+ site, Ca2+ is bonded in a 4-coordinate geometry to eight O2- atoms. There are a spread of Ca–O bond distances ranging from 2.31–2.83 Å. There are eight inequivalent Cu+2.33+ sites.
