Materials Data on Cu(BrN3)2 by Materials Project

Abstract

CuN6(Br)2 crystallizes in the tetragonal I4/mmm space group. The structure is one-dimensional and consists of four hydrobromic acid molecules and two CuN6 ribbons oriented in the (0, 0, 1) direction. In each CuN6 ribbon, Cu2+ is bonded in a linear geometry to two equivalent N2- atoms. Both Cu–N bond lengths are 1.83 Å. There are two inequivalent N2- sites. In the first N2- site, N2- is bonded in a distorted single-bond geometry to one Cu2+ and four equivalent N2- atoms. All N–N bond lengths are 1.65 Å. In the second N2- site, N2- is bonded in a 4-coordinate geometry to four N2- atoms. Both N–N bond lengths are 1.83 Å.
