Materials Data on Zn2As2O7 by Materials Project
Abstract
Zn2As2O7 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. there are three inequivalent Zn2+ sites. In the first Zn2+ site, Zn2+ is bonded to five O2- atoms to form ZnO5 trigonal bipyramids that share corners with five AsO4 tetrahedra, an edgeedge with one ZnO6 octahedra, and an edgeedge with one ZnO5 trigonal bipyramid. There are a spread of Zn–O bond distances ranging from 2.00–2.11 Å. In the second Zn2+ site, Zn2+ is bonded to six O2- atoms to form distorted ZnO6 octahedra that share corners with six AsO4 tetrahedra and edges with three ZnO5 trigonal bipyramids. There are a spread of Zn–O bond distances ranging from 2.06–2.23 Å. In the third Zn2+ site, Zn2+ is bonded to five O2- atoms to form ZnO5 trigonal bipyramids that share corners with five AsO4 tetrahedra and edges with two equivalent ZnO6 octahedra. There are a spread of Zn–O bond distances ranging from 1.97–2.11 Å. There are three inequivalent As5+ sites. In the first As5+ site, As5+ is bonded to four O2- atoms to form AsO4 tetrahedra that share a cornercorner with one ZnO6 octahedra, a cornercorner with one AsO4 tetrahedra, and corners with four ZnO5 trigonal bipyramids.
