Cu(SO4)2N2 crystallizes in the triclinic P-1 space group. The structure is one-dimensional and consists of eight ammonia molecules and one Cu(SO4)2 ribbon oriented in the (1, -1, 1) direction. In the Cu(SO4)2 ribbon, there are two inequivalent Cu2+ sites. In the first Cu2+ site, Cu2+ is bonded in a distorted rectangular see-saw-like geometry to four O2- atoms. There is two shorter (1.89 Å) and two longer (1.91 Å) Cu–O bond length. In the second Cu2+ site, Cu2+ is bonded in a rectangular see-saw-like geometry to four O2- atoms. There are a spread of Cu–O bond distances ranging from 1.88–1.90 Å. There are four inequivalent S2+ sites. In the first S2+ site, S2+ is bonded in a tetrahedral geometry to four O2- atoms. There are a spread of S–O bond distances ranging from 1.45–1.55 Å. In the second S2+ site, S2+ is bonded in a tetrahedral geometry to four O2- atoms. There is two shorter (1.46 Å) and two longer (1.54 Å) S–O bond length. In the third S2+ site, S2+ is bonded in a tetrahedral geometry to four O2- atoms. There are a spread of S–O bond distances ranging from 1.45–1.55 Å. In the fourth S2+ site, S2+ is bonded in a tetrahedral geometry to four O2- atoms. There are a spread of S–O bond distances ranging from 1.46–1.54 Å. There are sixteen inequivalent O2- sites. In the first O2- site, O2- is bonded in a single-bond geometry to one S2+ atom. In the second O2- site, O2- is bonded in a bent 120 degrees geometry to one Cu2+ and one S2+ atom. In the third O2- site, O2- is bonded in a bent 120 degrees geometry to one Cu2+ and one S2+ atom. In the fourth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Cu2+ and one S2+ atom. In the fifth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Cu2+ and one S2+ atom. In the sixth O2- site, O2- is bonded in a bent 120 degrees geometry to one Cu2+ and one S2+ atom. In the seventh O2- site, O2- is bonded in a single-bond geometry to one S2+ atom. In the eighth O2- site, O2- is bonded in a distorted single-bond geometry to one S2+ atom. In the ninth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Cu2+ and one S2+ atom. In the tenth O2- site, O2- is bonded in a single-bond geometry to one S2+ atom. In the eleventh O2- site, O2- is bonded in a single-bond geometry to one S2+ atom. In the twelfth O2- site, O2- is bonded in a single-bond geometry to one S2+ atom. In the thirteenth O2- site, O2- is bonded in a single-bond geometry to one S2+ atom. In the fourteenth O2- site, O2- is bonded in a bent 120 degrees geometry to one Cu2+ and one S2+ atom. In the fifteenth O2- site, O2- is bonded in a single-bond geometry to one S2+ atom. In the sixteenth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Cu2+ and one S2+ atom.
