Materials Data on Cu(NO3)2 by Materials Project

Abstract

Cu(NO3)2 crystallizes in the orthorhombic Pbcn space group. The structure is three-dimensional. there are two inequivalent Cu2+ sites. In the first Cu2+ site, Cu2+ is bonded in a 4-coordinate geometry to seven O2- atoms. There are a spread of Cu–O bond distances ranging from 1.97–2.70 Å. In the second Cu2+ site, Cu2+ is bonded in a square co-planar geometry to four O2- atoms. There are two shorter (1.99 Å) and two longer (2.02 Å) Cu–O bond lengths. There are three inequivalent N5+ sites. In the first N5+ site, N5+ is bonded in a trigonal planar geometry to three O2- atoms. There are a spread of N–O bond distances ranging from 1.22–1.31 Å. In the second N5+ site, N5+ is bonded in a trigonal planar geometry to three O2- atoms. There are a spread of N–O bond distances ranging from 1.22–1.32 Å. In the third N5+ site, N5+ is bonded in a trigonal planar geometry to three O2- atoms. There are a spread of N–O bond distances ranging from 1.23–1.29 Å. There are nine inequivalent O2- sites. In the first O2- site, O2- is bonded in a single-bond geometry to one N5+ atom. In the second O2- site, O2- is bonded in a single-bond geometry to one N5+ atom. In the third O2- site, O2- is bonded in a water-like geometry to one Cu2+ and one N5+ atom. In the fourth O2- site, O2- is bonded in a water-like geometry to one Cu2+ and one N5+ atom. In the fifth O2- site, O2- is bonded in a 2-coordinate geometry to two equivalent Cu2+ and one N5+ atom. In the sixth O2- site, O2- is bonded in a distorted water-like geometry to two Cu2+ and one N5+ atom. In the seventh O2- site, O2- is bonded in a water-like geometry to one Cu2+ and one N5+ atom. In the eighth O2- site, O2- is bonded in a water-like geometry to one Cu2+ and one N5+ atom. In the ninth O2- site, O2- is bonded in a single-bond geometry to one Cu2+ and one N5+ atom.
