Materials Data on CuBr4(NO)2 by Materials Project
Cu(OBr)2N2(Br)2 crystallizes in the tetragonal P4_2/mnm space group. The structure is one-dimensional and consists of four hydrobromic acid molecules; two Cu(OBr)2 ribbons oriented in the (0, 0, 1) direction; and two N2 ribbons oriented in the (0, 0, 1) direction. In each Cu(OBr)2 ribbon, Cu2+ is bonded in a linear geometry to two equivalent O2- atoms. Both Cu–O bond lengths are 1.86 Å. O2- is bonded in a distorted trigonal planar geometry to one Cu2+ and two equivalent Br2+ atoms. Both O–Br bond lengths are 2.09 Å. Br2+ is bonded in a 2-coordinate geometry to two equivalent O2- atoms. In each N2 ribbon, N3- is bonded in a linear geometry to two equivalent N3- atoms. Both N–N bond lengths are 3.08 Å.
