Materials Data on Na3CuAsCO7 by Materials Project
Abstract
Na3CuCAsO7 crystallizes in the monoclinic P2_1/m space group. The structure is three-dimensional. there are two inequivalent Na1+ sites. In the first Na1+ site, Na1+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Na–O bond distances ranging from 2.41–2.71 Å. In the second Na1+ site, Na1+ is bonded to seven O2- atoms to form distorted NaO7 pentagonal bipyramids that share corners with two equivalent NaO7 pentagonal bipyramids, corners with two equivalent AsO4 tetrahedra, an edgeedge with one NaO7 pentagonal bipyramid, an edgeedge with one AsO4 tetrahedra, and a faceface with one NaO7 pentagonal bipyramid. There are a spread of Na–O bond distances ranging from 2.26–2.89 Å. Cu2+ is bonded in a 5-coordinate geometry to six O2- atoms. There are a spread of Cu–O bond distances ranging from 1.99–2.60 Å. C4+ is bonded in a trigonal planar geometry to three O2- atoms. There is two shorter (1.29 Å) and one longer (1.32 Å) C–O bond length. As5+ is bonded to four O2- atoms to form AsO4 tetrahedra that share corners with four equivalent NaO7 pentagonal bipyramids and edges with two equivalent NaO7 pentagonal bipyramids. There are a spread of As–O bond distances ranging from 1.69–1.75more »
