A new trithiocarbonato Mo complex(Et_4N)_2[(S_2)Mo2O_2(μ-S)_2(CS_3)]was obtained from asystem 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 anddifference Fourier synthesis methods.Least squares refinement using 2910 reflections withI>3σ(I)converged to R=0.054.The CS_3~(2-) iigand in the complex chelates to Mo atom andvalues of the C-S bond distances in the CS_3~(2-) ligend indicate a substantial contribution ofthree resonance forms.
A new trithiocarbonato Mo complex (Et_4N) _2 [(S_2) Mo_2O_2 (μ_ S) _2 (CS_3)] was obtained from asystem containing MoO_4 ~ (2 -), S_x ~ 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 differential 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 CS bond distances in the CS_3 ~ (2-) ligend indicate a substantial contribution ofthree resonance forms.
