Abstract

The crystal structure of Cr(CO) 5(SCMe 2) has been determined by three-dimensional single crystal X-ray analysis. The compound crystallizes in the monoclinic space group P2 1/ a with a = 10.468(8), b = 11.879(5), c = 9.575(6) Å and β = 108.14(9)°. Least squares refinement of 1435 reflections resulted in a final conventional crystallographic discrepancy factor of R = 0.075. The coordination around the chromium atom is essentially octahedral; the CrC distance opposite the Me 2CS group is significantly shorter, 1.835(12) Å, than the remaining CrC CrSC angle is 120.8(4)°, and the chromium atom deviates from the plane described by the Me 2CS moiety by only 0.2 Å.
