Bis[benzyl(methyl)ammonium] tetrasulfidotungstate(VI)

B. R. Srinivasan, S. V. Girkar and P. Raghavaiah

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-HS and C-HS interactions, the strength and number of which can explain the observed W-S bond distances.
