Abstract:
The title compound, (C8H12N)(2)[WS4], was synthesized by the aqueous reaction of ammonium tetrasulfidotungstate(VI) with benzyl( methyl) amine in a 1:2 molar ratio.The compound is isotypic with the corresponding Mo analogue, (C8H12N)(2)[MoS4], and its structure consists of a slightly distorted tetrahedral [WS4](2-) dianion and two crystallographically independent benzyl( methyl) ammonium cations, with all atoms located in general positions.The cations and anion are linked by weak N-H...S and C-H...S interactions, the strength and number of which can explain the observed W-S bond distances.
