title: 1,3-Propanediammonium tetrathiotungstate and N,N,N',N'-tetramethylethylenediammonium tetrathiotungstate.
abstract: The title complexes, (C(3)H(12)N(2))[WS(4)] and (C(6)H(18)N(2))[WS(4)], contain tetrahedral [WS(4)](2-) dianions, which accept a complex series of hydrogen bonds from the organic dications. The strength and number of these hydrogen bonds affect the W-S distances.
