The crystal structure described by NH4 is Silicon tetrafluoride-like structured and crystallizes in the cubic P-43m space group. The structure is zero-dimensional and consists of one ammonium molecule. N(1) is bonded in a tetrahedral geometry to four equivalent H(1) atoms. H(1) is bonded in a single-bond geometry to one N(1) atom. is represented by the CIF card [CIF]
