| Ein neuer Zugang zu Tetrathiooxalaten. Die Kristallstruktur von (NEt4)2[C2S4]  | | | | Abstract
| (N E t4)2S5 was prepared from N E t4Cl and N a 2S4 in ethanol. Its reaction with boiling acetoni-trile yielded tetraethylammonium tetrathiooxalate. (N E t4)2[C2S4] was also obtained by heating (N E t4)2S5 with tetraethylammonium dithioacetate in ethanol. Benzyltriethylammonium tetra thiooxalate, (N E t3Bz)2[C2S4] • 2 toluene, crystallized after N E t3BzCl and N a 2S4 were heated in acetonitrile on subsequent addition o f toluene. The crystal structure o f (N E t4)2[C2S4] was de termined by X-ray diffraction (454 independent observed reflexions, R = 0.047). Crystal data: tetragonal, a = 871.2(1) pm, c = 1566.0(3) pm, space group P 4 2/nmc, Z = 2. The [C2S4]2-ion has point symmetry 4 m 2 (D 2d), i.e. the dihedral angle between the two CS2 groups is 90°. The ethyl groups o f the N E t4+ ions are disordered in two orientations. | | | |
