Cu2N crystallizes in the tetragonal P4/mmm space group. There are two inequivalent Cu sites. In the first Cu site, Cu(1) is bonded in a linear geometry to two equivalent N(1) atoms. In the second Cu site, Cu(2) is bonded in a square co-planar geometry to four equivalent N(1) atoms. N(1) is bonded to two equivalent Cu(1) and four equivalent Cu(2) atoms to form a mixture of edge and corner-sharing NCu6 octahedra. The corner-sharing octahedra are not tilted.
Cu2N crystallizes in the tetragonal P4/mmm space group. There are two inequivalent Cu sites. In the first Cu site, Cu(1) is bonded in a linear geometry to two equivalent N(1) atoms. Both Cu(1)-N(1) bond lengths are 1.88 Å. In the second Cu site, Cu(2) is bonded in a square co-planar geometry to four equivalent N(1) atoms. All Cu(2)-N(1) bond lengths are 2.07 Å. N(1) is bonded to two equivalent Cu(1) and four equivalent Cu(2) atoms to form a mixture of edge and corner-sharing NCu6 octahedra. The corner-sharing octahedra are not tilted.
