Materials Data on Se2NO6 by Materials Project

N2(SeO3)4 is Ammonia-derived structured and crystallizes in the orthorhombic P2_12_12_1 space group. The structure is zero-dimensional and consists of four ammonia molecules and eight SeO3 clusters. In each SeO3 cluster, Se is bonded in a trigonal planar geometry to three O atoms. All Se–O bond lengths are 1.63 Å. There are two inequivalent O sites. In the first O site, O is bonded in a single-bond geometry to one Se atom. In the second O site, O is bonded in a single-bond geometry to one Se atom.
