Crystal and molecular structure of di-µ-methylthio-(bis-
-cyclopentadienyltitanium)tetracarbonylmolybdenumGwyneth R. Davies and B. T. Kilbourn
The structure of di-µ-methylthio-(bis-
-cyclopentadienyltitanium)tetracarbonylmolybdenum has been determined by X-ray methods (space group Pbca, a= 15·842, b= 15·437, c= 14·992, R= 0·052 for 1535 |Fo| > 35e). The complex contains a planar four-membered ring system [graphic omitted]Ti–S–Mo–S[graphic omitted] with a Ti 
Mo distance of 3·32 Å(Ti–S 2·46 and Mo–S 2·56 Å; Mo–S–Ti 83°). A metal–metal interaction is postulated to account for the geometry of the ring system. Both methylthio-groups lie on the same side of the heterocyclic ring, the complex examined is therefore the cis-isomer. The interaction of these thiol groups with the mutually staggered cyclopentadienyl rings probably accounts for the stability of the cis- relative to the trans-isomer.
