Materials Data on Cu(N2O3)2 by Materials Project
Cu(N2O3)2 is Protactinium structured and crystallizes in the orthorhombic Pbca space group. The structure is zero-dimensional and consists of four copper, diamminebis(nitrato-kappao)- molecules. Cu2+ is bonded in a distorted linear geometry to two equivalent N+2.50+ and two equivalent O2- atoms. Both Cu–N bond lengths are 1.93 Å. Both Cu–O bond lengths are 1.89 Å. There are two inequivalent N+2.50+ sites. In the first N+2.50+ site, N+2.50+ is bonded in a distorted single-bond geometry to one Cu2+ atom. In the second N+2.50+ site, N+2.50+ is bonded in a trigonal planar geometry to three O2- atoms. There are a spread of N–O bond distances ranging from 1.23–1.35 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a single-bond geometry to one N+2.50+ atom. In the second O2- site, O2- is bonded in a bent 120 degrees geometry to one Cu2+ and one N+2.50+ atom. In the third O2- site, O2- is bonded in a single-bond geometry to one N+2.50+ atom.
