Title: Materials Data on Zn(AsO2)2 by Materials Project

Abstract

Zn(AsO2)2 crystallizes in the monoclinic P2_1/c space group. The structure is two-dimensional and consists of two Zn(AsO2)2 sheets oriented in the (0, 0, 1) direction. Zn2+ is bonded to four O2- atoms to form corner-sharing ZnO4 tetrahedra. There are two shorter (2.00 Å) and two longer (2.01 Å) Zn–O bond lengths. There are two inequivalent As3+ sites. In the first As3+ site, As3+ is bonded in a distorted T-shaped geometry to three O2- atoms. There are a spread of As–O bond distances ranging from 1.80–1.85 Å. In the second As3+ site, As3+ is bonded in a distorted T-shaped geometry to three O2- atoms. There are a spread of As–O bond distances ranging from 1.79–1.85 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a trigonal planar geometry to two equivalent Zn2+ and one As3+ atom. In the second O2- site, O2- is bonded in a trigonal planar geometry to two equivalent Zn2+ and one As3+ atom. In the third O2- site, O2- is bonded in a bent 120 degrees geometry to two As3+ atoms. In the fourth O2- site, O2- is bonded in a bent 120 degrees geometry to two As3+ atoms.
