1 Source of material

(NH4)2WS4 (0.010 g, 0.029 mmol) and BenzylMe3NCl (0.016 g, 0.086 mmol) were charged to a Pyrex tube with diameter of 9 mm and about 0.5 mL 1:4 (v/v) H2O/MeOH mixture was added as a solvent. While the solvent was being frozen, the Pyrex tube was evacuated under vacuum and sealed with the use of a flame. The sealed tube was placed in an oven and heated at 80 °C for a day, then cooled to room temperature. Yellow orange crystals were isolated by filtration and washed with MeOH and diethyl ether several times. Crystals of (BenzylMe3N)2[WS4] were obtained in 57 % yield, based on the W used.

2 Experimental details

H atoms were positioned geometrically and treated as riding, with C–H = 0.94 (aromatic CH), 0.98 (CH2) and 0.97 (CH3) Å with Uiso(H) = 1.2 (1.5 for methyl) Ueq(C). H atoms of the CH3 were positioned to be staggered with respect to the shortest other bond to the atom to which the CH3 is attached.

3 Comment

The tetrathiotungstate [WS4]2− anion, along with the tetrathiomolybdate [MoS4]2−, is one of the most extensively studied and structurally characterized thiometallate anions. Cations used for the stabilization of the [WS4]2− anion include NH4+, 5 , 6 Rb+, 7 [Ni(tren)2]2+ (tren = tris(2-aminoethyl)amine), 8 Ph4P+, 9 tetraalkylammonium (Me4N+, Et4N+, Pr4N+), 10 alkylammonium with N–H bonds present (H3NCH2CH2NH32+, i–PrNH3+, etc.), 11 , 12 , 13 , 14 , 15 and mixed tetraalkylammonium (BuMe3N+). 16 The title compound, {(C6H5CH2)(CH3)3N}2[WS4], was prepared by the solvothermal reaction of (NH4)2WS4 and (C6H5CH2)(CH3)3NI in a 1:4 (v/v) H2O/MeOH mixture as the solvent, and it is composed of a [WS4]2− molecular anion and two charge-balancing BenzylMe3N+ cations. Besides BuMe3N+, BenzylMe3N+ is another unsymmetrical mixed tetraalkylammonium cation suitable for the stabilization of the [WS4]2− anion.

In the structure of (BenzylMe3N)2[WS4], there are four crystallographically independent cations and two crystallographically independent [WS4]2− anions. The tetrahedral coordination geometry around the W atoms in both [WS4]2− anions is slightly distorted, with S–W–S bond angles between 104.98(9)° and 111.34(7)° for W(1) and between 107.86(8)° and 111.41(7)° for W(2). The W–S bond distances range from 2.155(2) to 2.198(2) Å for W(1) and from 2.161(2) to 2.198(2) Å for W(2). Compared to other [WS4]2− compounds (BenzylMe3N)2[WS4] shows slightly greater Δ values for the difference between the longest and shortest W–S bond distances, which are 0.043 Å for W(1) and 0.037 Å for W(2). The shortest S⋯H distance of 2.685(2) Å occurs between S(7) and H(11A), and there are three additional S⋯H contacts less than 2.80 Å in the pairs of S(4)⋯H(12B), S(2)⋯H(1A), and S(6)⋯H(14B).
