NSe is red selenium-derived structured and crystallizes in the monoclinic C2/c space group. The structure is zero-dimensional and consists of four NSe clusters. There are three inequivalent N sites. In the first N site, N(1) is bonded in a bent 120 degrees geometry to two equivalent Se(1) atoms. In the second N site, N(2) is bonded in a bent 120 degrees geometry to one Se(1) and one Se(2) atom. In the third N site, N(3) is bonded in a bent 120 degrees geometry to two equivalent Se(2) atoms. There are two inequivalent Se sites. In the first Se site, Se(1) is bonded in a water-like geometry to one N(1) and one N(2) atom. In the second Se site, Se(2) is bonded in a water-like geometry to one N(2) and one N(3) atom.

In the first N site, N(1) is bonded in a bent 120 degrees geometry to two equivalent Se(1) atoms. Both N(1)-Se(1) bond lengths are 1.80 Å. In the second N site, N(2) is bonded in a bent 120 degrees geometry to one Se(1) and one Se(2) atom. The N(2)-Se(1) bond length is 1.80 Å. The N(2)-Se(2) bond length is 1.81 Å. In the third N site, N(3) is bonded in a bent 120 degrees geometry to two equivalent Se(2) atoms. Both N(3)-Se(2) bond lengths are 1.81 Å. There are two inequivalent Se sites. In the first Se site, Se(1) is bonded in a water-like geometry to one N(1) and one N(2) atom. In the second Se site, Se(2) is bonded in a water-like geometry to one N(2) and one N(3) atom.
