The compound described by N2(H3(SeO3)2)2 crystallizes in the orthorhombic P2_12_12_1 space group. The structure consists of four ammonia atoms inside a H3(SeO3)2 framework. In the H3(SeO3)2 framework, there are three inequivalent H sites. In the first H site, H(1) is bonded in a linear geometry to one O(2) and one O(6) atom. In the second H site, H(2) is bonded in a linear geometry to one O(3) and one O(4) atom. In the third H site, H(3) is bonded in a single-bond geometry to one O(1) and one O(5) atom. There are two inequivalent Se sites. In the first Se site, Se(1) is bonded in a trigonal non-coplanar geometry to one O(1), one O(2), and one O(6) atom. In the second Se site, Se(2) is bonded in a trigonal non-coplanar geometry to one O(3), one O(4), and one O(5) atom. There are six inequivalent O sites. In the first O site, O(3) is bonded in a distorted water-like geometry to one H(2) and one Se(2) atom. In the second O site, O(4) is bonded in a bent 120 degrees geometry to one H(2) and one Se(2) atom. In the third O site, O(5) is bonded in a distorted bent 120 degrees geometry to one H(3) and one Se(2) atom. In the fourth O site, O(6) is bonded in a bent 120 degrees geometry to one H(1) and one Se(1) atom. In the fifth O site, O(1) is bonded in a distorted water-like geometry to one H(3) and one Se(1) atom. In the sixth O site, O(2) is bonded in a water-like geometry to one H(1) and one Se(1) atom. is represented by the CIF file [CIF]
