Cd2Se3O14N2O crystallizes in the monoclinic P2_1/m space group. The structure consists of two hydroxylamine, o-amino- molecules inside a Cd2Se3O14 framework. In the Cd2Se3O14 framework, Cd(1) is bonded to one O(3), one O(4), one O(5), one O(6), one O(7), and one O(8) atom to form CdO6 octahedra that share  a cornercorner with one Se(1)O4 tetrahedra and corners with four equivalent Se(2)O4 tetrahedra. There are two inequivalent Se sites. In the first Se site, Se(1) is bonded to one O(1), one O(2), and two equivalent O(3) atoms to form SeO4 tetrahedra that share corners with two equivalent Cd(1)O6 octahedra. The corner-sharing octahedral tilt angles are 54°. In the second Se site, Se(2) is bonded to one O(4), one O(5), one O(6), and one O(7) atom to form SeO4 tetrahedra that share corners with four equivalent Cd(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 51-55°. There are eight inequivalent O sites. In the first O site, O(7) is bonded in a bent 120 degrees geometry to one Cd(1) and one Se(2) atom. In the second O site, O(8) is bonded in a single-bond geometry to one Cd(1) atom. In the third O site, O(1) is bonded in a single-bond geometry to one Se(1) atom. In the fourth O site, O(2) is bonded in a single-bond geometry to one Se(1) atom. In the fifth O site, O(3) is bonded in a bent 120 degrees geometry to one Cd(1) and one Se(1) atom. In the sixth O site, O(4) is bonded in a bent 120 degrees geometry to one Cd(1) and one Se(2) atom. In the seventh O site, O(5) is bonded in a bent 120 degrees geometry to one Cd(1) and one Se(2) atom. In the eighth O site, O(6) is bonded in a bent 120 degrees geometry to one Cd(1) and one Se(2) atom.
