Title: Materials Data on Cd2As2O7 by Materials Project

Abstract

Cd2As2O7 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. Cd2+ is bonded to six O2- atoms to form distorted CdO6 pentagonal pyramids that share corners with six equivalent AsO4 tetrahedra and edges with three equivalent CdO6 pentagonal pyramids. There are a spread of Cd–O bond distances ranging from 2.27–2.40 Å. As5+ is bonded to four O2- atoms to form AsO4 tetrahedra that share corners with six equivalent CdO6 pentagonal pyramids and a cornercorner with one AsO4 tetrahedra. There is three shorter (1.71 Å) and one longer (1.76 Å) As–O bond length. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Cd2+ and one As5+ atom. In the second O2- site, O2- is bonded in a linear geometry to two equivalent As5+ atoms. In the third O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Cd2+ and one As5+ atom.
