MgWAgS4NH4 crystallizes in the monoclinic C2 space group. The structure consists of two ammonium molecules inside a MgWAgS4 framework. In the MgWAgS4 framework, Mg(1) is bonded in a rectangular see-saw-like geometry to two equivalent S(1) and two equivalent S(2) atoms. W(1) is bonded in a tetrahedral geometry to two equivalent S(1) and two equivalent S(2) atoms. Ag(1) is bonded in a 4-coordinate geometry to two equivalent S(1) and two equivalent S(2) atoms. There are two inequivalent S sites. In the first S site, S(1) is bonded in a distorted trigonal non-coplanar geometry to one Mg(1), one W(1), and one Ag(1) atom. In the second S site, S(2) is bonded in a distorted trigonal non-coplanar geometry to one Mg(1), one W(1), and one Ag(1) atom.
