Title: Materials Data on Ca7Cu17O24 by Materials Project

Abstract

Ca7Cu17O24 crystallizes in the orthorhombic Pmm2 space group. The structure is three-dimensional. there are four inequivalent Ca2+ sites. In the first Ca2+ site, Ca2+ is bonded to six O2- atoms to form a mixture of distorted edge and corner-sharing CaO6 octahedra. The corner-sharing octahedra tilt angles range from 47–49°. There are a spread of Ca–O bond distances ranging from 2.23–2.58 Å. In the second Ca2+ site, Ca2+ is bonded to six O2- atoms to form a mixture of distorted edge and corner-sharing CaO6 octahedra. The corner-sharing octahedra tilt angles range from 46–49°. There are a spread of Ca–O bond distances ranging from 2.25–2.55 Å. In the third Ca2+ site, Ca2+ is bonded to six O2- atoms to form distorted CaO6 octahedra that share a cornercorner with one CaO6 octahedra, a cornercorner with one CuO6 octahedra, and edges with two equivalent CaO6 octahedra. The corner-sharing octahedra tilt angles range from 29–44°. There are a spread of Ca–O bond distances ranging from 2.25–2.48 Å. In the fourth Ca2+ site, Ca2+ is bonded to six O2- atoms to form a mixture of distorted edge and corner-sharing CaO6 octahedra. The corner-sharing octahedral tilt angles are 44°.
