Abstract

NH3CH2(NO)2H2SeO2 crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of four ammonia molecules; four H2SeO2 clusters; and four ~{n},~{n}'-dihydroxymethanimidamide molecules. In each H2SeO2 cluster, there are two inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. In the second H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. Se2- is bonded in a distorted L-shaped geometry to two O2- atoms. Both Se–O bond lengths are 1.85 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to one H1+ and one Se2- atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to one H1+ and one Se2- atom.
