A new trithiocarbonato Mo complex(Et_4N)_2[(S_2)Mo2O_2(μ-S)_2(CS_3)]was obtained from a system containing MoO_4^(2-),S_x^(2-),and CS_2 and characterized by IR and X-ray structural analysis. The complex crystallizes in the (?)onoclinic space group P2_1/c with a=9.539(3)(?), b=20.745(2)(?),c=15.452(2)(?),β=94.58(2)°,and Z=4.The structure was solved by direct and difference Fourier synthesis methods.Least squares refinement using 2910 reflections with I>3σ(I)converged to R=0.054.The CS_3^(2-) iigand in the complex chelates to Mo atom and values of the C-S bond distances in the CS_3^(2-) ligend indicate a substantial contribution of three resonance forms. 展开更多

The solution was then heated and refluxed for half an hour. After cooling a bit, 20ml anhydrous ethanol saturated with HCl and 0.5g (Et4N)I were added to the solution. The brown twin crystals were crystallized in three days. The formula of the product was confirmed by elemental chemical analysis. Found: Mo, 36.09; Cl, 26.84; C, 15.19; H, 3.54; N, 1.76.
