The material structure described by NH4IO4 is Silicon tetrafluoride-derived structured and crystallizes in the tetragonal I4_1/a space group. The structure is zero-dimensional and consists of four ammonium molecules and four IO4 clusters. In each IO4 cluster, O(1) is bonded in a single-bond geometry to one I(1) atom. I(1) is bonded in a tetrahedral geometry to four equivalent O(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
