Title: Materials Data on CaZnAsHO5 by Materials Project

Abstract

CaZnAsHO5 crystallizes in the orthorhombic P2_12_12_1 space group. The structure is three-dimensional. Ca2+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Ca–O bond distances ranging from 2.34–2.67 Å. Zn2+ is bonded to six O2- atoms to form ZnO6 octahedra that share corners with four equivalent AsO4 tetrahedra and edges with two equivalent ZnO6 octahedra. There are a spread of Zn–O bond distances ranging from 1.97–2.28 Å. As5+ is bonded to four O2- atoms to form AsO4 tetrahedra that share corners with four equivalent ZnO6 octahedra. The corner-sharing octahedra tilt angles range from 40–59°. There are a spread of As–O bond distances ranging from 1.72–1.74 Å. H1+ is bonded in a single-bond geometry to two O2- atoms. There is one shorter (0.99 Å) and one longer (1.74 Å) H–O bond length. There are five inequivalent O2- sites. In the first O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Ca2+, one Zn2+, and one As5+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to one Ca2+, two equivalent Zn2+, and one H1+ atom. In the third O2- site, O2- is bonded in a 4-coordinate geometrymore » to two equivalent Ca2+, one Zn2+, and one As5+ atom. In the fourth O2- site, O2- is bonded in a 4-coordinate geometry to one Ca2+, two equivalent Zn2+, and one As5+ atom. In the fifth O2- site, O2- is bonded in a 1-coordinate geometry to two equivalent Ca2+, one As5+, and one H1+ atom.« less
