The crystal structure described by NbO8(NH4)3 is Indium-derived structured and crystallizes in the tetragonal I-42m space group. The structure is zero-dimensional and consists of six ammonium molecules and two NbO8 clusters. In each NbO8 cluster, Nb(1) is bonded in a distorted hexagonal bipyramidal geometry to four equivalent O(1) and four equivalent O(2) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 2-coordinate geometry to one Nb(1) and one O(2) atom. In the second O site, O(2) is bonded in a 2-coordinate geometry to one Nb(1) and one O(1) atom. is represented by the CIF file [CIF]
