Materials Data on CuSNO3 by Materials Project
(CuSO3)2N2 crystallizes in the trigonal R-3m space group. The structure is two-dimensional and consists of six ammonia molecules and three CuSO3 sheets oriented in the (0, 0, 1) direction. In each CuSO3 sheet, Cu3+ is bonded to one S2- and three equivalent O2- atoms to form CuSO3 tetrahedra that share corners with three equivalent SCuO3 tetrahedra. The Cu–S bond length is 2.20 Å. All Cu–O bond lengths are 1.98 Å. S2- is bonded to one Cu3+ and three equivalent O2- atoms to form SCuO3 tetrahedra that share corners with three equivalent CuSO3 tetrahedra. All S–O bond lengths are 1.50 Å. O2- is bonded in a bent 150 degrees geometry to one Cu3+ and one S2- atom.
