In the title compound, NH4+·(C2H5O)2PS2−, the ammonium cation is connected by four charge-assisted N—H⋯S hydrogen bonds to four tetrahedral O,O′-diethyl dithiophosphate anions, forming layers parallel to (100). The polar and non-polar constituents of the layers are stacked alternately along . Interlacing of the external ethyl groups through van der Waals interactions combines these layers into a three-dimensional structure.
