Synthesis and Crystal Structure of 1-Methylsulfinyl-1-methylthio-2-cyano-2-phenylethylene

摘要

The crystal of the title compound （C 11H 11NOS2, Mr =237.33） has been prepared and determined by X-ray single crystal diffraction. The crystal is monoclinic, space group P21/c with parameters : a=5.484 （1）, b=7.793（2）, c=28.295（6）, β=90.277（4）°, V=1209.2（5）3, Z=4, Dc=1.034 g/cm3, μ（MoKα）= 0.413 mm -1, F（000）=496, the final R=0.0390 and wR=0.1051 for 1500 observed reflections with I>2σ（I）. The X-ray analysis result shows that the orientation of methylsulfinyl and phenyl is the cis and confirms the E-stereochemistry of the title compound.
