NH4N5S4O is alpha Niobium phosphide structured and crystallizes in the monoclinic C2/m space group. The structure is zero-dimensional and consists of four ammonium molecules and four N5S4O clusters. In each N5S4O cluster, there are three inequivalent N sites. In the first N site, N(1) is bonded in a water-like geometry to one S(1) and one S(2) atom. In the second N site, N(2) is bonded in a bent 120 degrees geometry to one S(2) and one S(3) atom. In the third N site, N(3) is bonded in a bent 120 degrees geometry to one S(1) and one S(3) atom. There are three inequivalent S sites. In the first S site, S(1) is bonded in a tetrahedral geometry to one N(3), two equivalent N(1), and one O(1) atom. In the second S site, S(2) is bonded in a bent 120 degrees geometry to one N(1) and one N(2) atom. In the third S site, S(3) is bonded in a trigonal non-coplanar geometry to one N(3) and two equivalent N(2) atoms. O(1) is bonded in a single-bond geometry to one S(1) atom.
