Materials Data on As(NO2)2 by Materials Project

Abstract

AsNO3NO crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of four nitroxyl molecules and four AsNO3 clusters. In each AsNO3 cluster, As5+ is bonded in a water-like geometry to two O2- atoms. There is one shorter (1.64 Å) and one longer (1.97 Å) As–O bond length. N+1.50+ is bonded in a water-like geometry to two O2- atoms. There is one shorter (1.21 Å) and one longer (1.39 Å) N–O bond length. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a single-bond geometry to one As5+ atom. In the second O2- site, O2- is bonded in a single-bond geometry to one N+1.50+ atom. In the third O2- site, O2- is bonded in a bent 120 degrees geometry to one As5+ and one N+1.50+ atom.
