Abstract

Preparations and X-ray structure determinations are described for Ph3SiSPh and [W (CO) 4 (μ-SPh)] 2. The compound Ph3SiSPh crystallizes in space group Pcab with a= 15.260 Å, b= 15.968 Å, c= 16.757 Å, Z= 8, d calc= 1.20 g cm-3 (MoKα1, λ= 0.70930 Å). The structure was solved with MULTAN and refined to the final R= 0.050 for 1933 significant reflections. The molecule has an unusual CS-Si angle of 99.5° and a short Si-S bond length of 2.156 Å. ...
